If you need to change default mail delivery port of Postfix mail server from 25 to any other port lets say to 995. Here is how:

Edit /etc/postfix/master.cf  – a small note to make here is master.cf is located on same location on mostly all Linux distributions as well as FreeBSD.

Find line with:

smtp      inet  n       –       n       –       –       smtpd

Change smtp – which is actually a reference for port 25 to whatever port you need – i.e. 995 After change line should look like:

995      inet  n       –       n       –       –       smtpd

Saveconfig file and restart postfix to load new settings:

# /etc/rc.d/postfix restart
postfix/postfix-script: stopping the Postfix mail system
postfix/postfix-script: starting the Postfix mail system
