Question

When I am on my home wifi I can send e-mail.  When I am not on my home e-mail but on a wifi network or using the 3g network I cannot send e-mail.  HELP HOW TO FIX.

Answer 1

I know this question is a few years old now, but I recently found myself having the exact same issues;
Using my iphone or ipad at home created no problems at all, but I couldn't send e mails when away from my home network.
I recently switched broadband supplier at home and set up a new e mail address, then my problems began!
I openly admit I'm not great with technology and, to be honest, some of the answers provided on these forums confuse me more than the questions!
But this worked for me:
I went along the lines that the fault wasn't with my idevice but possibly with the broadband provider (in my case Plusnet) so I contacted their customer support.
They referred me to the set up process shown below;
From your home screen press Settings.
From the setting menu, choose Mail, Contacts, Calendars followed by Add Account…
From the Add Account… menu choose Other.
Fill in your Full Name, Email Address, Password and Description and press Next.If you need help with these, there's more detail underneath the screenshot.
Full name: Enter your name (or the name you'd like people to see when you send them email)
Email Address: Enter the address you're setting up, this could be a Plusnet address ([email protected]) or a hosted domain address ([email protected])
Password: Enter the password for your email address (I don't know what this is)
Description: Enter a useful description of the email address you're setting up (e.g. Mum's email). You can put whatever you want here
Press Next to continue.
More settings will appear. Some will already be filled in.Enter the Incoming and Outgoing Mail Server details and press Next. If you need help with these, there's more detail underneath the screenshot.
IMAP/POP This will default to IMAP - it's up to you which one you want to use (I don't know what to choose)
Incoming Mail Server settings
Host Name: For IMAP this is imap.plus.net - for POP, this is mail.plus.net
User Name & Password: Enter the username and password for the email address you're setting up (I don't know what these are)
Outgoing Mail Server settings
Host Name: relay.plus.net
User Name & Password: These are optional, but if you want to send mail while on the move (e.g. while connected to mobile or wireless networks), we recommend filling these in.Enter the username and password for the email address you're setting up (I don't know what these are)
When you're finished, press Next.
If the box shown below appears, press Yes (you may need to do this twice).
After a minute or two, your email address will be set up and ready to use.If you chose IMAP when setting up you’ll be able to choose whether you want to use Notes (if you chose POP you’ll be taken back to the settings screen from step 2). Press Save when you’re done.
That's all you need to do. To start checking your email, go back to your home screen and press Mail.
Now I fully understand that it may be different for each broadband provider but the processes must be similar.
The key appears to be in setting up the outgoing message server settings in step 5. Where it says "optional, but if you want to send mail while on the move (e.g. while connected to mobile or wireless networks), we recommend filling these in.

Where it says "we recommend" I think it should read "you must fill these in"
I went back to Settings - Mail,Contacts, Calenders - click on the offending account and click on the account shown.
Under OUTGOING MAIL SERVER click on the server, in my case relay.plus.net, and click again to show the details. make sure you enter your user name and password and after a few seconds the account will verify and show a load of ticks.
I tried this on my phone this morning while on 3G only. I sent an email to another of my addresses and immediately got the response that the message couldn't be sent as the recipient was rejected and the message had been placed in my Outbox. I followed the above steps and immediately heard the satisfying "whoosh" as my mail was sent. 10 seconds later another satisying beep as my e mail arrived at my alternate account.
Hope this helps anyone else with a similar problem.
