          Priority: P2
            Bug ID: 6842
          Assignee: dev@spamassassin.apache.org
           Summary: Spamc should have an option to only try v4 addresses
                    when hostnames are specified with -d.
          Severity: normal
    Classification: Unclassified
                OS: Mac OS X
          Reporter: sabugs@gushi.org
          Hardware: PC
            Status: NEW
           Version: 3.3.2
         Component: spamc/spamd
           Product: Spamassassin

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.

> This is a pretty simple enhancement

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.
