I'm getting this message in my mail.log:

/usr/share/perl5/IO/Socket/IP.pm line 646.
I'm running debian stable with Spamassassin from backports:
SpamAssassin Server version 3.4.0
running on Perl 5.14.2
and libmail-dkim-perl version 0.39 from stable (wheezy)
I see from this thread on gossamer that this may have something to do
with
libmail-dkim-perl:

Has anyone made any progress on this? Anyone found a workaround?
Yes, it's the same issue. The bug is in perl, fixed in 5.18 or later.
A minimal test program triggering the bug was posted in the mentioned
thread by me on 2014-10-29.
A workaround is setting your recursive DNS resolver to return
minimal responses, as suggested by alessio in that thread.
The fix is to upgrade perl. I considered reporting the issue
to perl, but I doubt anyone would care to backport the fix
to old versions, so I didn't.
