Q: Can receive Mail but not send?

http://support.apple.com/kb/TS3899

Sounds like the SMTP settings which manage outgoing mail

follow above doc

sounds like the carrier is blocking it not that the settings are set wrong

if the carrier is blocking it you have 2 options

1 get the carrier to not block it

2 use a web client as it would be using port 80 like normal surfing which the carrier would not be able to block

iOS: Unable to send or receive email

Configuration problems with IMAP e-mail on iOS with a non-standard SSL port.

Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts   Tap on the Account, then on the red button that says Remove Account.
