Using doveadm penalty I just noticed a penalty for 0.0.0.0.
Is this Postfix querying the auth-socket for his SASL-requests?
I tried adding 0.0.0.0 to login_trusted_networks, but that doesn't help.

Maybe a portscan? Sometimes they turn up as 0.0.0.0

Most likely. 0.0.0.0 would in any case mean "unknown". It shouldn't show up in penalty though..
