Performance between SpamAssassin 3.2.1 and 3.2.2 and 3.2.3

Fri Aug 17 10:09:05 IST 2007

Oh, there is a way to uninstall SA, look in CPAN's FAQ here for a perl
script to do it:

  http://www.cpan.org/misc/cpan-faq.html#How_delete_Perl_modules

But, I suggest that you try instead to install the patch from
spamassassin bug 5589 (
http://issues.apache.org/SpamAssassin/show_bug.cgi?id=5589 ), which, by
harvesting async DNS results ASAP, should speed things up, and then do a

  spamassassin -D -t <quarantined spam email>

and look at the output to see where the delays are.

Choose an email which has a uri in the body so that the uridnsbl code in
SA is triggered.

And check your rbl_timeout value.  It might need reducing to a sensible
setting.

And please feed back to the SA bugzilla.

Cheers,

Phil
