I am trying to send emails from an existing email account. I have just changed to T-Mobile. The error I get when trying to send emails is "Cannot Send Email" "The recipient firstname.lastname@example.org was rejected by the server because it does not allow relaying".

Thanks for responding.
I'm using a specific email client (bigpond).
Jason Y from T-Mobile on FB gave me the following solution at it fixed the problem.
Thanks for your help.
Go to Settings - Mail, Contacts, Calendar and select your email account. Tap on Account, then go down to the "Outgoing Mail Server" and tap on SMTP. You will then see that is says optional under User Name and password but go ahead and provide that information and see if that resolves your issue.
