I don't believe the problem is related to ClamAV (if you really are
using clamd), but rather spamd eating your CPU when high number of
emails is queued for scanning by qmail-scanner.
Try if this helps:
- Limit number of connections qmail-smtpd may accept (-c option, with
your specs. set it to 50 or lower, check memory/cpu load)
- Ensure you've enough clamd threads
- Ensure that you limit number of spamd threads (and count how many are
used - if to many unused lower the number)
- When under load, check that cpu usage is 100 % (if not, you're
probably swapping memory - lower the number of qmail-smtpd
connections)
- Ensure you've access to a fast DNS server (if spamd is doing RBL
checks)
- Use badmailfrom/badmailto - it may help you filter unneeded smtp
connections
(Optionally renice the qmail-send/qmail-remote user to ensure that email
queued for remote delivery gets enough cpu)
Best regards,
