Don't know about the rest of the world, but I'm seeing a big rise in
spam over the last 48 hours or so (4 fold increase); could that
account for your spikes? From what I've seen the new tactic seems to
be multiple threads so it's almost a DOS. Also my greylists are taking
a pounding (I'm eternally grateful they are in a different thread
pool); almost to the minute the greylisting expires the hits are back.

Seems Feb is gonna be an interesting month if this is anything to go
by.

No, awl is not enabled. also custom rules are less than 100K so i think 
this should not be an issue but still i see hight cpu usage by spamd.

spamc 3.1.1 and procmail

[".rp" <pr...@moveupdate.com>]

Hi,

In our system wide .procmail I have been using /usr/bin/spammassin. Recently the 
CPU usage has soared when spamassassin ran so I decided to use /usr/bin/spamc 
with spamd running as a dameon. 

well, it didn't quite work. here is a sample problem:
| /usr/bin/spamc -u $LOGNAME


 sendmail[21908]: l19HQGne021908: from=<bounce-422420-
1377318@lists.now.org>, size=18119, class=0, nrcpts=1, msgid=<LYRIS-1377318-
422420-2007.02.09-08.29.35--xyzsom#xyz.com@lists.now.org>, proto=SMTP, 
daemon=Daemon0, relay=lists.now.org [198.65.157.134]
 spamd[17291]: spamd: connection from localhost [127.0.0.1] at port 56232
 spamd[17291]: spamd: setuid to xyzsom succeeded
 net spamd[17291]: spamd: creating default_prefs: 
/home/xyzsom/.spamassassin/user_prefs
 net spamd[17291]: mkdir /root/.spamassassin: Permission denied at 
/usr/lib/perl5/vendor_perl/5.8.0/Mail/SpamAssassin.pm line 1469
 net spamd[17291]: config: cannot write to /home/xyzsom/.spamassassin/user_prefs: 
Permission denied

I also tried spamc with no parameters but that did not help.
So what changes do I need to make? Will this adversly affect running 
/usr/bin/spamassassin ?
