The standardised port for SMTP submission is 587. See 
http://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol specifically 
"Although some servers support port 465 for legacy secure SMTP in 
violation of the specifications"

However. gmail do actually support both 587 with TLS *and* 465 with SSL 
on connect, on smtp.gmail.com.
