Urgent Problem

[ProxUser3000]

Hi,
today i modified the Proxmox SMTP Banner from ESMTP Proxmox to our mail gateway name.
As there were no problemes in the queues i thought everything is okay, but later my user reportet no mail is outgoing.

I changed it back, but still nothing is working.

What can i do?

i get errors like this:
Aug 21 19:19:27 mail postfix/smtpd[1001]: warning: smtpd_client_event_limit_exceptions: non-null host address bits in "myipchangedbymeforforum/24", perhaps you should use "myipchangedbymeforforum/24" instead
Aug 21 19:19:27 mail postfix/smtpd[1001]: warning: mynetworks: non-null host address bits in "myipchangedbymeforforum/24", perhaps you should use "myipchangedbymeforforum/24" instead

if you censor the ip this way, nobody can tell you what the actual problem is, but from the error i guess you have a non null part in the ip like so: x.y.z.155/24 when it really has to be x.y.z.0/24
