In this case
1 WEB mail still won't get scanned....?
2 If I point all my mail clients' smtp settings to the virus scanner using
dns(assuming I separated my DNS entries for SMTP and POP...)...if the virus
scanner dies(and they do), then essentially all local users lose ability to
send mail.....?

Imail is untouched, DNS was modified to
original
anydomain.com MX 10 virusgate.ISPdomain.com
virusgate.ISPdomain.com MX 10 virusgate.ISPdomain.com
mail.anydomain.com MX 10 imail.anydomain.com
In the above scheme, local users send their outgoing to
mail.anydomain.com, and it gets routed to Imail and delivered within
Imail, no scanning.
But for scanning local-to-local mail:
anydomain.com MX 10 virusgate.anydomain.com
virusgate.ISPdomain.com MX 10 virusgate.anydomain.com
mail.anydomain.com MX 10 virusgate.anydomain.com
Now local users send to mail (ie, no need to chagne their mail pgms
at all), it gets routed to virusgate, is scanned, and virusgate
forwards to the !! ip address !! of Imail, and Imail delivers the
scanned mail locally.
There is no mail loop because the virus scanner's "next hop" for any
Imail mailhost is not via an MX query, but by virusgate's internal
routing table, or even its NT hosts file.
