I experienced a similar issue on a RHEL3 with another spam filter
The server was not busy, yet false high load was detected and shutdown
my sendmail ports due to threshold settings.
The issue was eventually resolved.

The bug was tracked on:  

The following updated kernel listed here:

I hope this helps.

Hi there,

Just a heads up. We recently retired an older e-mail gateway we have and
put centos 4.3 on it. After a yum upgrade a new kernel was installed. 
Specifically Linux Kernel 2.6.9-42.0.2.ELsmp.

MailScanner does not perform well on this hardware platform with that
kernel, at all. Infact the load artificially goes over 30.

Anyways the fix for us was to revert to vmlinuz-2.6.9-11.ELsmp and all
is well since. Back to processing 200k mails a day without issue.
