Description Dan Mahoney 2012-09-26 05:58:35 UTC 
This is a pretty simple enhancement.

Imagine a setup where spamd lives on a different host, but because of a previously-filed-bug, only listens on one address class -- and the admin has chosen to use v4.  (Perhaps by specifying -i without an ip address).

What I'm suggesting is an enhancement to discard AAAA records from the semantics used to look up addresses for -d.  This is useful both where v4 connectivity is more stable than v6 (for example, when tunnels are in play), while still benefitting from the benefits of hostname-mapping rather than embedding an ip in a config file.

It turned out not to be so trivial, lots of details to handle  :)

Please try it out: either the spamc from trunk, or apply the attached patch
to earlier versions.
