Hello,

please first try to open the ports in system firewall or with IPTables rules by following

https://support.rackspace.com/how-to/open-ports-in-the-linux-firewall-to-access-pop-and-imap-mail-servers/

Keep in mind that IPTables rules are usually reseted on system reboot by default. Not sure how it is in CentOS case.

If that does not help, please check also output of the command

netstat -nltp | grep 25

which checks if there is actually any application listening on that port.

Hello,
I’ve sent this via email and now duplicating here: the firewall is off, the issue has nothing to do with it. 2 additional IPs are working fine, port 25 is open for those that have two blocked ones:
89.221.217.218
89.221.217.217
Please double check and fix this.
Regards.
