I am using IPv6 myself with dovecot, so I doubt that's the problem.Very right, it was not an IPv6 problem. Aug 09 10:01:54 auth-worker(4431): Debug: sql(user at domain.com,1:2:3:4::5,<acTIaWysN8YgAQZ8LNQAEgAAAAAAAAAC>): allow_nets: Matching for network 0.0.0.0/0 Aug 09 10:01:54 auth-worker(4431): Info: sql(user at domain.com,1:2:3:4::5,<acTIaWysN8YgAQZ8LNQAEgAAAAAAAAAC>): allow_nets check failed: IP 1:2:3:4::5 not in allowed networks I included IPv6 addresses in the allow_nets and now all works great!
