Description Bastien Nocera 2006-05-08 06:51:55 EDT

The Spamassassin rules contains lookups to relays.visi.com, which can cause
excessive loads (and then timeouts) on the nameserver used.

Patch from Brad Hinson <bhinson@redhat.com> to disable those lookups (as in
Spamassassin 3.1) attached.

What kind of delays per message are you seeing?
Comment 4 Brad Hinson 2006-05-08 21:26:46 EDT
Check out these links:

relays.visi.com had two nameservers, ns1.visi.com and ns2.visi.com.  ns1 is
still working, but ns2 is not.  When dns queries go to ns2, there's a timeout of
about a couple of seconds.  Customer who reported this had heavy dns traffic,
and this timeout eventually caused all further requests to timeout, rendering
the nameserver useless until restarted.
