In the end it turned out that it was check_relay that was causing the performance problems. system averages of about 6 dropped to less than 1 when I turned off this plugin.
That's surprising. Is your relayclients file very large? If so then you might be able to compile it into a CDB file and use it as "morerelayclients".
check_relay clearly needs some documentation, btw!
I am not a perl programmer and so am not clear on what this plugin does. Is this what checks the rcpthosts file to check which domains we are receiving mail for? If not, what does it do and do I really need it?
You need it if you use the qpsmtpd as a mail relay to send mail to other domains. Most likely you'd notice pretty fast if you needed it. :-)
