[Mimedefang] Resource Question

[Cormack, Ken]

With what you are currently doing, your hardware is more than enough.  I run
a pair of dula-proc 800MHx Compaq DL380's with half the disk, 2GB of RAM,
1GB of swap, custom sendmail rulesets, MIMEDefang doing all kinds of
filtering, greylisting, SpamAssassin (which just had 7000+ additional
rawbody rules to it), commercial virus scanning, zip-file inspection, and
DNS.  My boxes handle an average of 50-80K connections a day, and process
about 2GB of mail each day.  During heaviest business hours, the primary box
has peaked at 47% CPU utilization.  Note that I also use a RAM disk to keep
I/O delays short.  My average email is 47K in size, with max size set at
50MB.  Greylisting also helps tremendously, by relieving the need for the
more CPU-intensive filtering.  Based on your mail flow and on what you do
with your boxes, you should be fine.

Subject: [Mimedefang] Resource Question


I am using Mimedefang 2.39.


My Mail server is a Pentium 2.4 GHZ with 2 gig of Ram.  I have a 4 Gig
Swap Drive.  I have a raided 70 Gig SCSI Drive.

On average,the combined incoming and outgoing messages number between
3,000 and 5,000.  The total volume is never more than 500 meg.

I don't do much with Mimedefang.  I bounce banned attachments, and add a
disclaimer to all outgoing emails.  In the future, I will have
Mimedefang BCC all outgoing emails assigned accounts.  I don't need
Mimedefang to do any Virus Checking.


I assume that the hardware that I am using is plenty and that I should
never run out of resources with my current Mimedefang Configuration.

Can somebody verify this.


Thanks
