Run MScanner in a virtualized environment.

[Guy Story KC5GOI]

I am running VMWare.  I have allocated off 1 gig of ram with a dual core 3
GHz Xeon, it runs Postgrey, Postfix, Mailscanner, ClamAV, and Spamassassin
for 100 employees.  I run 4 max childern and a scan interval of 10 seconds.
I do not have full stats on dropped connections.  According to AWStats for
this month so far:

51197 code 554 access denied
4210 code 450 DNS check failures, mailbox busy or other reasons
1286 code 550 relaying denied unknown users
13 code 999 unknown error

Our mail server is very responsive and solid.  The only time I see more than
the 10 second scan interval as a delay is the first time an address hits
Postgrey.  I have Postfix running rbls for me.  I prefer to deny the
connection so my load in general is reduced.

My rational for running in a vm is disaster recovery.  I back this vm up
monthly offsite.
