Why do you think you need to use port 25 in order to send email from a user to their own email server? Port 25 might be the default for SMTP server to server traffic, and historically has been used for client-to-server traffic; but these days most client-to-server traffic should go on port 587, the SMTP Submission port. http://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol#Ports
