Package: dovecot
Severity: normal
Tags: patch upstream
With this patch the program will always bind on both IPv4 and IPv6
addresses (when binding to [::] has been requested) no matter how the
system is configured.
This allows using a single daemon for IPv4 and IPv6 on modern Linux and
BSD systems.
Please forward the patch upstream.
