[Mimedefang] mimedefang and trend micro's interscan viruswall

[Xiaoyan Ma]

I am installing mimedefang2.29 for the first time on a Solaris 8 box 
running sendmail 8.12.8.  I run Trend Micro's Inter Scan Viruswall as virus 
filter and SpamAssassin as spam filter.

I have InterScan v3.6 for solaris sendmail switch version running.  When 
installing mimedefang, it sees the InterScan filter and when mimedefang is 
up running it rejects virus affected attachment.   But it doesn't seam to 
use inter scan's tools, such as iscan's viurs log, and other features in 
the intscan.ini file.

When I tried to run interscan as a separate plug-in, and I can then use all 
the tools.

My questions are:

1) If I run interscan trhough mimedefang, should I use the sendmail switch 
version or the standard Solaris version?

2) Should I be able to use interscan tools when running it through mimedefang?

3) CPU usage is one of our major concerns.  Will running interscan 
separately add a heavy load to the system?

Thanks for any help and suggestions.
