Send/Receive e-mail using Wifi OR GPRS - help!

Going away next week so I want to bea ble to check my POP3 NTL email via GPRS.
At the moment I have my XDA iiS set up so I can check the email via my WiFi connection at home. This works ok, and I can send or receive with no problems.
However, when I try to create a new Messaging account, I'm really struggling.
FYI, my mobile company is Virgin and my email ISP is NTL.
I've already created the standard GPRS connection through Virgin, which works for for internet browsing etc.
So far i've:
1 - created a new messaging account called "NTL via GPRS" (to differentiate from the wifi account)
2 - Input my NTL email address
3 - User Information - my usual NTL user name & password
4 - Account type is set to POP3
5 - Incoming Mail Server is set to POP.NTLWORLD.COM
6 - Outgoing Mail Server is set to SMTP.T-EMAIL.CO.UK (i believe this is because Virgin actually runs on the T-Mobile network?)
When I click on the send/receive button, the GPRS conection is made, but then all that happens is the progress indicator just says, "connecting..." for ages, then I get 2 error messages - "timed out waiting for server - please retry" - and "Messages cannot be dwnloaded to your mobile device. Make sure you are connected and that your email account settings are correct."
Does anyone have any idea what I'm doing wrong? Any help would be massively appreciated - thanks.

3 - User Information - my usual NTL user name.... did you set name only? try set [email protected]

Was anyone able to help here. I have exactly the same robelm with Tmobile in the UK. I would like to be able to send mail via GPRS but can't. I can receive it and I can do both on wifi.

The problem is some weard logic from the ISP's. You probably have an email account with the ISP that gets you your internet connections as well at home.
When using WiFi @ home you still send your email via your own ISP.
When you send email via GPRS, the email will be send via your GSM/GPRS provider of your sim-card which will be another telco/isp.
For some reason telco's/ISP won't allow you to send mail, using the smtp (outgoing mail) server of your own ISP. This is why it won't work via GPRS.
It very much depends on your telco company to get this working. I know the trick for vodafone in the Netherlands, but that won't help you I think. Most of the time some smart "googling" will help.
I my case the trick was to get an free account via the website of MyVodafone.nl
and on the PDA I defined an email account with an outgoing mail server that requires autentication and as autentication I used the u/p I created on the vodafone website. And the address of the outgoing mailserver in my case is authsmtp.vodafone.nl

Yahoo Mail

When I try to send messages it tells me that an error occurred and that it couldn't send the message. I don't know how this can be, because it retrieves my mail, it just won't send it. ???

You mean with Pocket Outlook using SMTP? (You must be a yahoo plus subscriber)
I have the same problem and managed to trace it down to the following:
The built in SMTP program does not authenticate itself 100% by the book. Can't tell exactly but I saw in the server log that it did something funny after HELO.
This causes some mail servers (on the receiving end) to ignore the mail entirely or think it's spam.
I only have this issue with my yahoo account though. Others (e.g. gmail) work fine from Outlook.
Hope it gets fixed in WM6...

T-mobile has a work around.
1) Go to T-Mobile and setup a email forwarding account (Set your phone as a MDA NOT A Dash
2) Turn off email forarding for incoming
3) ON Dash - Change outgoing SMTP to: myemail.t-mobile.com
4) Change user name (Use different than login - because you will still login to Yahoo using the pop or IMAP server to your10digitphonenumber:1
5) password is your yahoo password
Also change NO SSL on outgoing, and outgoing requires authentican checked.
This is also required if you use the dash as a modem on your laptop. I could not sent SMTP Trough T-mobile connectiosnt o laptop, but could if connected via a wifi connection that was not t-mobile.

I have wm6, it used to work. I will try that, but i don't see why it just stopped working all the sudden when it used to....

Problem Official WM6 smtp email

Hello
I didn't find any info this kind of problem what i have after updating mobile 6.
So i have email account on internet and i can receive mails to my tytn but cannot send any mail. i also try to start internet share and send mail with my computer but i get error what says "cannot connect smtp server" what the hell is wrong.
If i connect normaly my tytn to active sync i can send mails and receive mails with same setting thru my DSL. But with 3G or GPRS i cannot send mail. everything else is working and has been working before update to wm6.

What SMTP server are you using?
You should be using the one from your internet provider, which - when
using your mobile phone as internet acces device - is your mobile
operator.

I use my DSL internet provider mail service, It has been working exatly with same settings before, and now i'm able to receive all mails from imap.netikka.net mail server but cannot send email outgoing SMTP server "mail.netikka.fi"
I can send and receive emails with my computer thru DSL normaly so that mail server should be ok. Something has to be wrong in wm6 settings some security problem maby.

The mail server is ok, but quite often one cannot access an smtp server
from outside the providers' network (sometimes access is possible from
outside with a logon and a password). This is a common security measure to
avoid their mailservers being used for spam.
So if you connect via a provider A, you can fetch mail from anywhere, but
you should send mails via the smtp server provider A has (regardless of
where your mail comes from). If you then connect via a provider B, you can
again fetch your mails from anywhere, but you cannot use the smtp server
of provider A; you need the one provider B has.
Try first using the smtp server from your mobile provider, if that doesn't
work it is indeed something in wm6.

Thanks for info, I set now my phone operator outgoing smtp server address and now mails are going out also.
So case closed.

Actually, the smtp stuff gives rise a problem I also want to warn you for... If you connect to multiple networks with your TyTN (e.g. wifi and 3G), you basically would want to be able to change the smtp server to suit your needs (e.g. on wifi you need the smtp server of your dsl provider, on 3G the one of your mobile provider). There is no mechanism foreseen in Messaging to achieve this.
As a workaround, I duplicate my mail accounts, but with different outgoing settings (most just go back 3 days or so): i have for instance "mymailbox (provider one)" and "mymailbox (provider 2)". Depending on the network via which I connect, I need to select the appropriate mailbox before choosing "new" or "reply". This way, the correct smtp server is used when I send a mail. It is not an elegant solution, but I haven't found another way. If you have an smtp server that requires you to log on to send mails, chances are you can access that one from anywhere.
Jörg

Yes i have now that problem that in 3g network mail goes out but not my DSL wifi but i can live with that. But still it is quite weird that with WM5 my DSL provider smtp server works even 3g and wifi but not with WM6.

If you can log on to the smtp server, it could be possible to use it regardless of your connection.
Perhaps you can test it when you use your laptop to send emails, but connect via your mobile operator to internet. If that works, it ought to work with wm6;
but I doubt it to be possible without logon.

Agreed this is a flaw in WM6, shoul be possible to quickly toggle between different settings for SMTP.
I have the same problem, two years ago this was not an issue I could then use the smtp settings from our domain on phone and in office (dsl), this no longer works even with the DSL connection in the office we have to use smtp of the internet provider.

Yahoo Mail outgoing mail issues

I really have no idea what the problem is here. I used to be able to send emails fine when I had WM 6.0 installed. I upgraded to Kavana's 6.1 ROM which automatically found imap settings for Yahoo Mail.
Now I cannot seem to send emails but I can receive them fine. Every once in a while maybe every couple days I will be able to get a message to send out. I have tried different areas of town, recreating the email setup, even reloading the ROM. Nothing seems to help.
It's getting very frustrating not being able to send emails when I've just read an urgent one I've received!
Current settings are:
Incoming: imap.mail.yahoo.com
Outgoing: smtp.mobile.mail.yahoo.com (with authentication)
Any help much appreciated!

Are you using tmobile, and have you configured your by going to accessories and connection setup.

I've been having the EXACT same issues for the past 2 months! My outgoing Yahoo! mail worked fine for about 2-3 months (after flashing Kavana's 6.1), then all of a sudden none of my emails would go out. It's SOOO FRUSTRATING... I deleted my Yahoo! account, then set it up again. It worked for a day then went back to being crappy. It's gotta be an issue with Yahoo!'s outgoing servers, because Gmail works just fine via Dash.

Yes I have T-Mobile - forgot to mention that earlier - and Yes I have setup the data connection. Like I said before it works sometimes but usually it fails.
If I use the same setup on T-mobile's WM6 ROM it works fine. So something in Kavana's ROM is a little different. I have seen other postings on this forum and other forums with people having the same issue but never seen a resoltuion.
I have deleted, recreated, modified, manually setup, automatic setup, and used pretty much every configuration I could think of when setting this Yahoo! account up on Kavana's 6.1 but nothing works so far.

Actually I had that same problem with WM6. Whether or Not Emails would actually get sent was a crapshoot.so I used Y!Go

Funny you all mention this because I thought I was doing something wrong!
I had no problem with Yahoo at all until 6.1
Now I can't send OR receive mail..
Maybe Yahoo changed something?

Here's something that might help in this sending Yahoo! Mail problem. I found it out on the 'net; the solution has to do with the ports that Yahoo! uses to receive mail. I didn't want to post it until I had it running for at least a month without problems, and it seems to work.
Normally, Yahoo! uses port 25 to receive mail, but since that port is the most popular, it uses SPAM-screening routines on that port which ends up rejecting a lot of sending mail connections. But there are two other ports. One seemed to work really slow. But port 465 has worked for me for over a month, no problem at all, I can send every time.
Okay, so how to use it? Go into your Yahoo! email menu on your phone. Choose Tools > Options > Account Settings > Edit Account Setup. Press "Next" until you reach the "Outgoing (SMTP) mail server:" screen. Where it reads "smtp.mobile.mail.yahoo.com", add this at the end: ":465". (So the whole entry should read "smtp.mobile.mail.yahoo.com:465".) Go "Next" until you reach "Finish" then "Done." Then try it out.
I hope it works for you. Strangely enough, now I have occasional problems RECEIVING mail, but not sending. Oh, well, that I can live with.

XV6800 465 fix didnt work
the 465 fix didnt work with my XV6800 any other ideas?

even more weird...
I'm having the same problem, but it's only on one of my two yahoo accounts that will not send. Everthing was working fine until the upgrade to Rickywatt WM6.1. I have two different yahoo (well really SBCGLOBAL.net) accounts a business one and a personal one. I have been over them with a fine toothed comb and the settings are exactly the same, but only one of them is sending. They are both receiving just fine, but only one can send emails.
How weird is that?? I tried the 465 port change and I still get an error to "Be certain you have network coverage and try again" I'm stumped!

this should help man, i found the fix and posted it in another forum but this will do the trick.
anyone who has been having problems sending emails from yahoo or any other account try this fix, straight from our good buddies at microsoft....

Link is sending me to the wrong place
If I did this right. There is a cab file attached at the bottom somewhere that fixed my email. It is from microsoft and it's called "Windows Mobile 6.1 Hot Fix for Sending POP and IMAP E-mail" The link in the earlier post was taking me somewhere else. I hope this link takes you to the right place:http://www.microsoft.com/downloads/details.aspx?FamilyId=D9D71B2E-D2DD-44F2-86E5-1E53AAD7FB7A&displaylang=en
So far this has worked for me and Rickywatt version of WM6.1...I don't know if this will work on anything but WM6.1. There is a PC(msi) version and a CAB version. I used the cab version. Hope this helps others out too.

This cab seems incompatable with NightRavens 6.1 ROM.
I also have had similar issues with Yahoo setup in 6.1. The dropdown box that should allow for a choice between IMAP4 and POP3 is grayed out - it is not an option. So they force you to use IMAP4 when seemingly none of the server settings work correctly. Has anyone has any luck with IMAP4 settings in Yahoo?

pop mail sending problems
If you know how to modify the registry then you don't need the cab. It's really easy, and one of the posts linked to the exact instructions. A few months ago I tried to get this made into a sticky since it affects everyone with the 6.1 ROMs, and not being able to send email is a pretty major problem, but the XDA admins didn't seem to think it warranted a sticky. Lame.
Anyway, here's what you do:
It is fixed by adding a registry key called "Operator" (without the quotes) to HKEY_LOCAL_MACHINE\System\Inbox\Settings\
Then, inside the HKEY_LOCAL_MACHINE\System\Inbox\Settings\Operator key you add a String Value named "OutgoingServer" with value "127.0.0.1" (again, both without the quotes.) A soft reset should be done after saving this.

Incoming and Outgoing Mail Server Settings for Hotmail, Yahoo! Mail, GMail, AOL and more
the Google Gmail service offers a SMTP server (outgoing mail server) for Gmail accounts. To use the Google Gmail SMTP server, use the following information:
Google Gmail Outgoing Mail Server (SMTP): smtp.gmail.com
The Gmail SMTP server requires authentication (use the same settings as for the incoming mail server)
The Google Gmail SMTP Server requires an encrypted connection (SSL) on port 465.
Why & when do I need these settings?
Hotmail, Yahoo! Mail, GMail and other providers are basically email services designed to provide you with email mailbox accesss directly from the web. However, going online and logging on to their sites is not always the most convenient way for reading and sending emails.
On the other hand, you have the alternative to send and receive emails through such a mailbox by using a local email client software, such as Outlook Express, Microsoft Outlook, Thunderbird, Thunderbird, etc. In order to properly use it, you need to configure your email software with the incoming and outgoing mail servers of your email provider (Hotmail, Gmail, Yahoo! Mail or else).
Mail Server Settings
Hotmail Settings
As other web based email services, Hotmail is using the HTTP protocol for connecting you to your mailbox. If you want to send and receive Hotmail emails using an email client software, then your software must support Hotmail HTTP access for your email account. Some email clients, such as Outlook Express or Microsoft Outlook, offer builtin support for Hotmail accounts, so you only have to select HTTP when you are asked to select your email account type and select Hotmail as the HTTP Mail Service Provider.
Yahoo! Mail Settings
Unlike Hotmail, Yahoo! Mail offers standard POP3 access for receiving emails incoming through your Yahoo mailbox, by using your favorite email client software. To setup your email client for working with your Yahoo account, you need to select the POP3 protocol and use the following mail server settings:
Yahoo Incoming Mail Server (POP3) - pop.mail.yahoo.com (port 110)
Yahoo Outgoing Mail Server (SMTP) - smtp.mail.yahoo.com (port 25)
Google GMail Settings
The Google GMail service offers email client access for retrieving and sending emails through your Gmail account. However, for security reasons, GMail uses POP3 over an SSL connection, so make sure your email client supports encrypted SSL connections.
Google Gmail Incoming Mail Server (POP3) - pop.gmail.com (SSL enabled, port 995)
Outgoing Mail Server - use the SMTP mail server address provided by your local ISP or smtp.gmail.com (SSL enabled, port 465)
Lycos Mail Settings
The Lycos Mail Plus service allows you to use POP3 and SMTP servers for accessing your Lycos mailbox.
Lycos Mail Incoming Mail Server (POP3) - pop.mail.lycos.com (port 110)
Outgoing Mail Server - smtp.mail.lycos.com or use your local ISP SMTP mail server
AOL Mail Settings
The AOL email service is a web based system, designed for managing your AOL mailbox via HTTP IMAP access. Unlike Hotmail, you can use any email client to access your AOL mailbox, as long as it supports the IMAP protocol.
AOL Incoming Mail Server (IMAP) - imap.aol.com (port 143)
AOL Outgoing Mail Server - smtp.aol.com or use your local ISP SMTP mail server
Mail.com Mail Settings
The Mail.com email service allows you to use POP3 and SMTP servers for accessing your Mail.com mailbox.
Mail.com Mail Incoming Mail Server (POP3) - pop1.mail.com (port 110)
Outgoing Mail Server - use your local ISP SMTP mail server
Netscape Internet Service Mail Settings
The Netscape e-mail system is web-based, which means you can access their e-mail from any Internet connection. Netscape Internet Service also supports AOL® Communicator, Microsoft® Outlook, Microsoft® Outlook Express, and other POP3 e-mail software. The outgoing mail server needs SSL support, so make sure your email client software supports SSL connections over the SMTP protocol.
Netscape Internet Service Incoming Mail Server (POP3) - pop.3.isp.netscape.com (port 110)
Netscape Internet Service Outgoing Mail Server - smtp.isp.netscape.com (port 25, using a secure SSL connection)
Tiscali Mail Settings
The Tiscali email service allows you to use POP3 and SMTP servers for accessing your Tiscali mailbox.
Tiscali Incoming Mail Server (POP3) - pop.tiscali.com (port 110)
Outgoing Mail Server - use your local ISP SMTP mail server
Freeserve Mail Settings
The Freeserve email service allows you to use POP3 and SMTP servers for accessing your Freeserve mailbox.
Freeserve Incoming Mail Server (POP3) - pop.freeserve.com (port 110)
Outgoing Mail Server - use your local ISP SMTP mail server
Supanet Mail Settings
The Supanet email service allows you to use POP3 and SMTP servers for accessing your Supanet mailbox.
Supanet Incoming Mail Server (POP3) - pop.supanet.com (port 110)
Outgoing Mail Server - use your local ISP SMTP mail server
If your email client does not support Hotmail as a Mail Service Provider or if it simply doesn't work with your mail server settings, you can use a 3rd party solution like Hotmail Popper, IzyMail, POP Peeper or Email2Pop. When using such tools, you should define your Hotmail account as a POP3 account and you will need to define your incoming mail server will as 'localhost' (or 127.0.0.1).

Even with that registry tweak I have run into outgoing Yahoo issues today with the plus.smtp.mail.yahoo.com:465 server. That has always worked for me in the past - incoming still OK.

OutgoingServer case sensitive?
I think the registry key name is case sensitive.
I assume you reset your phone after setting the registry. Is it possible that you changed the case on one or more of the letters in OutgoingServer? I think that the mail program ignores the key if the case is not exact.

It works!
Just adding here that this hot fix (URL below) worked for me when I needed to fix the broken outgoing mail function for Yahoo mail on an HTC 5800 using Windows 6.1 Mobile...
http://www.microsoft.com/downloads/...2E-D2DD-44F2-86E5-1E53AAD7FB7A&displaylang=en
(I first connected the HTC to my laptop, then downloaded the software hot fix to the laptop and it went from there straight to the phone.)

Desire HTC mail POP/IMAP manual setup not working?

Hi all,
I got my Desire yesterday. It is a gorgeous device, but has one fatal flaw. The POP/IMAP manual e-mail setup in HTC mail is not working.
Gmail or Hotmail work fine - there is no need for a manual setup, the phone does it for you.
But Yahoo, or any other custom mail does not work. When setting up the incoming and outgoing mail server, the phone gets stuck at the incoming mail server setting and doesn't advance to the outgoing server setting as it should.
After you set up the incoming mail server you hit next and the phone checks online and a popup says "Verifying account settings". After this is done, I believe it should advance to outgoing server settings, but it doesn't and gets stuck at the incoming server settings screen...
This is a very fatal mistake and problem - one of the main functions of a smartphone not working...
Can you guys see if it works for you - maybe its only my unit that is faulty?

I got it set it up on my University IMAP fine, I had this issue but just had to change the security type to TSL.

Unfortunately that doesn't work for me...
It is very weird, as the same settings worked with K-9 mail app without any issues...

I got the same issue so I use K-9 Mail instead (which I prefer since it seems to push my emails faster)

I can't get it to sign in to gmail. I have a @googlemail account, and it just fails to verify account information every time. All other mail accounts, Hotmail and proper POP3, work fine.

That's cause you use the Gmail app for Googlemail, not the normal mail app

I prefer to use the HTC mail widget. Anyway, I got the thing going now, by connecting via imap instead.

I'm in touch with HTC customer service and we're trying to figure out what is wrong. I'll set up a test account for them so that they can test it and see why the e-mail is not being set-up. Will update later...

i set up gmail as an exchange server.. Only done it half hour ago but it should be push now

I'm also having this same issue. (Trying to use SSL.)

Anyone manage to made Yahoo Mail wotking on IMAP? I have an YahooPlus account and I can connect using a WM device, but no chance with Desire [using the same settings as in WN device]. On Desire, it stuck on first step - setting of incoming IMAP mail server, saying each time "wrong username/pw"....

Have you tried using the stock Android mail app which can be found here:
http://rhedgehog.com/apk/email.apk
I prefer this to the HTC Sense mail app and its much more flexible/configurable during the set-up phase, I had problems with my Uni account swapped to this and no problems since then using IMAP, POP and SMTP

I also have difficulties getting IMAP+SSL to work with the HTC mail application.
I suspect it has something to do with the certificate. The server I'm trying to connect to doesn't have a verified certificate, and you don't get prompted to accept the certificate, as you do if you use the K-9 mail app.

I had same kind of problems with Hero after upgrading to android 2.1.
Problem seems to be related to setup procedure. It is not able to prompt certificate acceptance dialog. But if you setup account with address that is not existing or where is not imaps service running it will say that it can't verify account but you are able to continue. After creating account launch mail application, go to settings and put real server name. At this point it will prompt certificate acceptance dialog and after that it is working.

I of course had the same trouble on my Aria but managed to get it working by following these instructions:
first open mail.
enter manual setup.
INCOMING:
as for settings:
protocol: Imap
Email: [email protected]
user name: youraccount
password: your password
IMAP server: imap.mail.yahoo.com
security type: none
server port:143
OUTGOING:
login required is checked
user name: youraccount
password: your password
SMTP server: smtp.mobile.mail.yahoo.com
security type: none
server port: 587
NOTE: if it still wont let you set up incoming server, try first entering in a non-existent server. such as imap.mail.yahoo.commm or something. it will give you an error message but hit continue. NOT OK! from there set up outgoing correctly.
then exit.
then launch mail app and select that account. click menu-more-settings-account settings and enter the correct server address.
hopefully this works for you guys as it did for me.
--Edit--
forgot to add, if possible, make sure wifi is off.

also, I have discovered that htc mail wont log in unless you are SIGNED OUT of your yahoo account everywhere else. i had my laptop automatically loading yahoo's web pasge and i guess it was messing it up. so sign out of yahoo mail before closing your browser.
hope this helps.

sent my yahoo and my talktalk account up on my phone..fine!
HOWEVER!!!!!!!!!!!!
I had to do this on my WiFi as it would not connect over 3G...
