Sendmail, MimeDefang & Spamd ??

[Marcelo Maraboli <ma...@usm.cl>]

Hello

I have Sendmail 8.12.11 + MimeDefang -2.40 running the
perl version of SpamAssassin 2.63 and my CPU is at 98%,
so I want to change to Spamd/Spamc, but I cannot find
the exact install procedure...

Is Spamd supported by MimeDefang ??  should I use
  milter-spamc/0.25 (beta) instead ??

atte,

First, I'd suggest upgrading to 2.64 or higher before going much
further. SA 2.63 is vulnerable to a DOS attack by messages with
specially malformed mime sections.

Do not run versions 2.50-2.63 on a production server due to the
potential for DoS.


Second, converting to spamc/spamd would be SLOWER for a MimeDefang
setup, not faster.

MimeDefang calls the SpamAssassin perl API's directly, a method that is
faster than using spamc/spamd, but is only usable by tools written in perl.

spamc/spamd is faster than calling the "spamassassin" command-line
script, but not faster than directly loading the API's.
