I have an iPad 1 and have set up 2 imap mail accounts, I use it a lot to receives mail whilst out and about but have noticed that I can send or receive with no problems when at home on wifi but can only receive mail when using 3G network. I get the message ' the connection to the outgoing server "smtp.ntlworld.com" failed. Additional outgoing mail severs can be configured in settings> mail, contact, calenders.' Any help would be greatly appreciated.
