You could essentially do that with just Declude and a bit of programming for stripping the attachments out of messages.

Regardless, having one scanner is not going to do a good enough job if you rely on F-Prot based on results from the last year.  I would recommend McAfee over F-Prot as a single scanner since it appears that they are more stable, though it is clear that any single scanner can have issues from time to time.

Thanks, Matt.

I only went for the Lite version because this is a gateway scanner.  The
internal mail servers are indeed protected by a different vendor's
product.

I'm setting up these two layers because my company prefers to quarantine
all viral messages, and then substitute any other inbound executables
with a text message in the original message.  This way, our users don't
receive unnecessary emails.

The "other" log line I'm seeing is independent of the usage of the /ai
switch.  As for investigation of the /ai switch, this email is part of
that due diligence!

Andrew,

A separate instance is set up for each message's attachments that are 
scanned, there is no cause for any concern.  MAXATONCE was designed for 
licensing reasons and shouldn't be used in most installations.  If you 
set MAXATONCE below the number of processes that might be launched (this

is a highly variable number), then it will cause overflow to occur or 
otherwise backup your system needlessly.

Regarding your other question, I believe that you are seeing this 
because you are using the /ai switch.  I don't use that switch, though I

couldn't say why exactly.  I have found however with many such things 
that their definitions of a non-virus that throw off such things might 
vary widely and include things such as encrypted zip files, something 
that Declude handles more flexibly.  It's always a good idea to get as 
much information about new or alternative switches before using them.  I

have found info in KB's, release notes, and also by E-mailing the 
companies.  These things aren't always as descriptive as you might want,

so dig deep.

I would also very strongly recommend a second scanner.  Simply put, 
things will sometimes not function properly.  There have been at least 4

occasions in about a year that F-Prot has messed up and would have 
caused significant virus leaking.  Currently I would recommend McAfee, 
but I would recommend ClamAV after a period of stability emerges since 
the daemon is faster than anything but F-Prot.  McAfee is of course a 
bit more responsible with their definitions, so if capacity isn't a 
problem, I would use that over ClamAV regardless.

I'm using the f-prot command line scanner, and the lines in the 
virus.cfg look like this:

SCANFILE        C:\F-Prot\fpcmd.exe /ai /type /silent /archive=5 /dumb
/noboot /nomem /packed /report=report.txt
VIRUSCODE 3
VIRUSCODE 6
REPORT  Infection:

That's working fine, but in my testing I'm only putting a few messages 
through at a time.  I note that the /report variable is setting one 
specific filename.  What happens when two or more declude processes are
    

  
launched and both want to call the virus scanner at the same time?  I 
realize that scanning is relatively quick, but I can see that 
collisions would result.

If Declude doesn't handle this internally to set a different report 
name per instance, then I think paranoia would pushe me to set 
MAXATONCE 1 ... ?

Andrew.
