Sounds like an outgoing mail server issue. Most times you can't access an outgoing mail server unless you are connected though the same provider's internet connection. This is to reduce spammers access to mail servers. I personally use a free mail2web exchange account and sync OTA. That way I do not have server issues. I have also used my gmail account's outgoing mail server with authentication. Works great also and does not tie you to any certain data connection.
