Question Non Standard SMTP Port

[Nick Wood]

Hey all,

Has anyone managed to configure Plesk to use a non standard SMTP port? eg: 30000. I've been trying all weekend and I'm having a heck of a time.

- I've reconfigured Postfix and etc/services to use the correct port.
- I've rebooted the Mail Manager
- I've rebooted Postfix and checked for errors (there are none)
- I've opened the firewall ports
- I can telnet in to the mail server from another system on a different IP.
- I can telnet into the system from the same IP


I have to say, I'm a little stumped.

Side note: RoundCube will not send mail either. I'm assuming because it can't connect to Postfix.


Help!

For Roundcube you can try to change smtp port in file /usr/share/psa-roundcube/config/defaults.inc.php as:

$config['smtp_port'] = 25;

Hi, I have google cloud, and the port 25 is blocked. So I tried to change the port to "2525 or 3000", and opened the port in ssh linux, but I put "iptables -A INPUT -p tcp --dport 2525 -j ACCEPT" and nothing happens. Now i try to send a email and said SMTP error(-1): connection to server failed. What can I do?
