Can Postfix use two SMTP port ?

Hello,

SMTP 25 port is default, how about add another port for SMTP? such as 2222??

Thanks

 

yes ..

edit /etc/postfix/master.cf

smtp inet n - - - - smtpd
2222 inet n - - - - smtpd

save .. restart postfix

 

Hello klamardo,

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.

Thanks

 

I know what now, home isp blocked those traffic, thanks.

 

OK now, 25 port blocked by home isp, port 2222 port can telnet.

Thanks !

 

Just tested, I can send email to external email server and also can receive email .
