[amorfo77]

issue #5709

If strict is True and host bits are set in the supplied address, then [ValueError](https://docs.python.org/dev/library/exceptions.html#ValueError) is raised. Otherwise, the host bits are masked out to determine the appropriate network address.

Hi, i have run the update 2024-01e, but the netfilter container still restart again and again.
Is it wrong that the mailcow is in the ip input table? Is something else, what i can do?

netfilter-mailcow-1 | MAILCOW target is in position 2 in the ip input table, restarting container to fix it...
netfilter-mailcow-1 exited with code 2
