are you using the correct authentication method and port number with gmail?
See for example:
https://mail.google.com/support/bin/answer.py?answer=13287&query=smtp&topic=0&type=f

"Please note that if your client does not support SMTP authentication,
you won't be able to send mail through your client using your Gmail
address."


As for imap, while I haven't done the actual setup, at work we use
dovecot to do our imap with postfix.   I think it is available in one
of Ubuntu's repository.
