* or postfix or control web panel
« on: August 19, 2022, 01:16:32 PM »
Few days ago I noticed a plenty of email messages denied by system in /var/log/maillog, system gone wild.
Zen spamhaus  org in combination with postfix configuration marked some incoming email servers as blacklisted servers, some of them weren't on spamhaus list at all.

I tested some IP addresses there:

Configuration of postfix wasn't changed for months.
Maybe anyone have more info about that problem? Is it spamhaus error/bug with false positive reporting or is there anything with the current system?

Code: [Select]

Thank you,
