Package: dovecot

The comment for the listen/ssl_listen statement is misleading:

  # IP or host address where to listen in for connections. It's not
  # currently possible to specify multiple addresses. "*" listens in
  # all IPv4 interfaces. "[::]" listens in all IPv6 interfaces, but
  # may also listen in all IPv4 interfaces depending on the
  # operating system.

First of all, if I specify [::], then dovecot 1.2 will only listen
on IPv6, not IPv4, independent of the net.ipv6.bindv6only setting.
This is a change from 1.0, where [::] with net.ipv6.bindv6only==0
would also accept IPv4 connections.

And second, the way to get IPv4+IPv6 both working is to specify

  *, [::]

which is a bit in contrast to what the comment says about multiple
addresses.

Thanks to Kurt Roeckx for help in debugging this.
