while I*DO* appreciate your suggestion, since I am fairly confident to say I

redefinition, I'm not too interested in proving that point by making those
changes on a production machine. Again, thanks anyway.
I am the ports maintainer for the FreeBSD version of SpamAssassin.
used 'it' for YEARS in production, (commercial product,) several
platforms, i386, amd64, FreeBSD versions 6.4-7.4.
ONE DAY, ONE BRAND NEW CLIENT was having real problems with their
mailq. email was backing up.
Two days to figure it out, I deleted the INET6 module (on freebsd, its a
lot easier, I suppose than on your linux thing).
Now, all the email flowed perfectly. SA was trying to do ipv6 lookups,
the kernel did NOT have ipv6 compiled in.. NONE OF OUR PRODUCTION
SYSTEMS DO, and there is no logical explanation for it.
SA does NOT need INET6, unless you have two things:
#0, INET6 compiled into your kernel
#1, INET6 dns server as the first server in /etc/resolv.conf
#2, INET6 firewall, routing, mx records, etc.
I updated FreeBSD port so that it did not even try to install INET6 pm
unless the system was compiled with INET6 in the kernel.
ymmv,
Did I mention that we were not able to reproduce this in the lab? and up
till then, no other client had a problem?
