postfix send mail on port other than 25
I have a home built server running out of my house with a dynamic ip. I'm using a dynamic dns service, so thats all good. The webserver, etc. is running fine.
I want to create my own mail server, and so I installed Postfix (no spamassasin, etc. etc.) and wanted to just get that working intially. I just learned that my ISP has port 25 blocked, so when I run from the command line:
Jan 19 18:41:41 localhost postfix/smtp: connect to gsmtp83.google.com[22.214.171.124]: Connection timed out (port 25) Jan 19 18:42:11 localhost postfix/smtp: connect to gsmtp163.google.com[126.96.36.199]: Connection timed out (port 25)
Can someone please tell me how do I configure postfix to send email on another port, like 465?
