SMTP 25 port is default, how about add another port for SMTP? such as 2222??
smtp inet n - - - - smtpd
2222 inet n - - - - smtpd
save .. restart postfix
I have followed yours to add 2222 port, but I found out can't telnet 25 and 2222, I can telnet 995, 465, 110, checked firewall is good.
I know what now, home isp blocked those traffic, thanks.
OK now, 25 port blocked by home isp, port 2222 port can telnet.
But you wont be able to use your server as mailserver then as no other external mailserver will try to connect to your server on port 2222.
Just tested, I can send email to external email server and also can receive email .
