Description Bastien Nocera 2006-05-08 10:51:55 UTC
spamassassin-3.0.5-3.el4

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> to disable those lookups (as in
Spamassassin 3.1) attached.

What kind of delays per message are you seeing?


Comment 4 Brad Hinson 2006-05-09 01:26:46 UTC
Check out these links:
http://mail-archives.apache.org/mod_mbox/spamassassin-users/200501.mbox/%3C6.2.0.14.0.20050104182350.02f4f418@192.168.50.2%3E
http://wiki.openrbl.org/wiki/VISI

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.
