Hi
We are running Qmail Scanner 1.25 + Spamassassin 3.04 + Clamd 1.86.1 on
our dual 1.4Ghz P3 Linux mail server. We've been experiencing some
problems with the server taking a long time to scan messages (In most
cases they are taking between 60 and 80 seconds). I have the following
rulesets installed:
70_sare_adult.cf 70_sare_unsub.cf init.pre
70_sare_bayes_poison_nxm.cf 72_sare_bml_post25x.cf last-update
70_sare_genlsubj0.cf 72_sare_redirect_post3.0.0.cf local.cf*
70_sare_header0.cf 88_FVGT_subject.cf mr_wiggly.cf
70_sare_html0.cf 90_FVGT.cf netcom.cf
70_sare_obfu1.cf 99_sare_fraud_post25x.cf nov2rules.cf
70_sare_oem.cf 99_sober.cf rolex.cf
70_sare_ratware.cf DomainDigits1.cf surbl.cf
70_sare_spoof.cf evilnumbers.cf weeds.cf
At the moment I have disabled Razor, SPF and RBL checks from within the
Spamassassin configuration.
Spamd is started from Daemontools (/service/spamd/run):
#!/bin/sh
exec /usr/local/bin/softlimit -m 50000000 /usr/bin/spamd -m 8
--username=qscand
Qmail-smtpd is also started from Daemontools (/service/qmail-smtpd/run):
#!/bin/sh
QMAILDUID=`id -u qmaild`
NOFILESGID=`id -g qmaild`
MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
LOCAL=`head -1 /var/qmail/control/me`
if [ -z "$QMAILDUID" -o -z "$NOFILESGID" -o -z "$MAXSMTPD" -o -z
"$LOCAL" ]; then
echo QMAILDUID, NOFILESGID, MAXSMTPD, or LOCAL is unset in
echo /var/qmail/supervise/qmail-smtpd/run
exit 1
fi
if [ ! -f /var/qmail/control/rcpthosts ]; then
echo "No /var/qmail/control/rcpthosts!"
echo "Refusing to start SMTP listener because it'll create an open
relay"
exit 1
fi
exec /usr/local/bin/softlimit -m 50000000 \
/usr/local/bin/tcpserver -v -R -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" -u
"$QMAILDUID" -g "$NOFILESGID" 0 smtp /usr/local/bin/rblsmtpd -r
spam.dnsbl.sorbs.net -r smtp.dnsbl.sorbs.net -r sbl-xbl.spamhaus.org -r
bl.spamcop.net sh -c '/var/qmail/bin/qmail-smtpd' 2>&1
The server has 1.5GB of memory so I was wondering if the softlimit needs
to be changed? Has anyone else had a problem with this sort of thing?
Thanks,
John
