How does one implement external virus scanning under IMS 5.1?

We have an iPlanet Messaging Server 5.1 mail server running

under Solaris that we are currently using to accept all incoming

mail. We also have an older Mirapoint appliance which performs

standalone smtp virus scanning that we would like to use with

the iPlanet server to perform antivirus scanning. For capacity

reasons, however, we cannot have all incoming messages be first

handled by the Mirapoint box (via MX records) and then

redirected to our iPlanet box. We were hoping to use a

(conversion?) channel to accomplish this by redirecting all

incoming messages with attachments to the Mirapoint box's smtp

server and then having the Mirapoint box resend the scanned

messages back to the iPlanet smtp server. [NOTE: the Mirapoint

machine cannot redirect messages to smtp servers not running on

port 25]

I realize that this is not the perfect approach to this problem

because of the potential for a mail loop, but I was hoping that

we could setup another filter to not perform the redirection

based on either headers in a message or the fact that it is

coming from the Mirapoint IP address.

Any ideas or hopefully even an example configuration of how to

achieve this would be greatly appreciated.

Thanks, in advance,

Steve

The conversion channel of iMS allows you to use any command line based virus scanner that runs on your platform. I'm a Solaris|Linux person myself and I know TrendMicro makes a comand line scanner for Solaris.

Since Mirapoint is the bottleneck why use it? Instead use the command line method I mention above. You'll probably see about a 20-25% increase in utilization on your iMS system by using the conversion channel to scan all mail. (I don't recall if it made it into 5.2 or not but there is or will be something that allows you to configure the conversion channel to only scan certain users mail, using something in LDAP to determine.)

Too bad about not running on a port other than 25. That was going to be my next suggestion.
