doveadm mailbox command fails if backend has an IPv6 address

15 Jan 2018


      Hi,
some of my maintenance scripts weren't working as expected and I finally
found that this only happens if the user was mapped to a backend server
reachable via IPv6:
On a director:
doveadm mailbox status -u username messages Junk
returns
Junk messages=203  (if backend is connected via IPv4)
or
Lookup of host ipv6addr:542 failed: ... (if backend is connected via IPv6)
doveadm_tcp_connect_port tried a net_gethostbyname with "ipv6addr:542"
as hostname.
I've attached a quick-and-dirty-patch (for 2.2.33.2) that fixes this (at
least for me).
Regards,
Andreas
