it means that Dovecot is trying to bind to an IPv6 interface, but your system doesn't support IPv6.
The solution is to tell Dovecot to only listen on an IPv4 interface. You can do this by adding the following to the very top of your /etc/dovecot.conf file

Code: Select all

listen = *
instead of

Code: Select all

listen = *, ::
