clamav load

[Zion Ahead]

What would cause such high clamav and mailnull load? How do I correct this?

Importantly, how do I trace which domain is spamming and which is getting spam from the outside? I do have phpsuexec enabled, spamassassin and clamav enabled.

Using centos 4.4. / cpanel stable

My exim constantly fails throughout the day too, even doing eximup --force doesn't stop that from happening

tail you exim_mainlog to see
make sure you are using :fai: & not blackhole for default accounts

you may not have users sending outboud spam (but then again you may)
you may be just getting a boatload of inbound junk

secure your mail server with some good RBL's there are plenty of how too's on these forums
