Description Kim Bisgaard 2025-12-31 10:00:25 UTC

Since dovecot was updated to 2.4 (for fedora 43) its logging format has changed enough that fail2ban does (silently) not work for dovecot-logs.

I have used the current upstream /etc/fail2ban/filter.d/dovecot.conf which work for 2.4 dovecot

Reproducible: Always




Additional Information:
# rpm -q dovecot fail2ban
dovecot-2.4.1-8.fc43.x86_64
fail2ban-1.1.0-13.fc43.noarch

Comment 1 Richard Shaw 2025-12-31 15:17:49 UTC

I tried pulling the new config into the build but now the internal testing fails so this has become a non-trivial problem.

Comment 2 Kim Bisgaard 2025-12-31 15:25:03 UTC

Bad luck :-(

I note that the 'mdre-aggressive' has not been corrected. But otherwise all fine from here
