Need Recommendations

[Mike Kercher]

I would HIGHLY recommend a local caching nameserver on your MX boxen.  You
might also consider using the clamavmodule instead of straight clamav.

2 MX servers with the following

Dual 933Mhz 1 Gig of memory
FC1  (mailscanner and spamassassin need to be upgraded)
mailscanner-4.31.6-1
spamassassin-2.63

1.7Mhz 512 Memory (desktop)
FC2
mailscanner-4.40.11-1
spamassassin-3.0.2-1

I am experiencing a slow down in the delivery/processing of email on my
MailScanner servers.  I receive roughly 50,000 emails on a daily basis and
if there is a delay in the processing of any emails it can get backed up
very quickly.  I'm not sure if it is a DNS timing issue?, would anyone
recommend using local DNS in this case, or does anyone use it and have they
seen improvements?  Can anyone recommend anything in the MailScanner.conf
file that may help?

I have "Max children" set to 10 on the server with dual process and 5 on the
server with one processor, and "queue scan interval" is set to 6 on both
servers as well.  I am using Clamav as my virus scanner.  Please let me know
if you need additional info, and thanks in advance for your assistance.
