antivirus.exim configuration

Hello,
I have a client who does not wish to have their e-mail attachments filtered. They on a regular basis receive bat, mdb, etc. files e-mailed to them from clients.

I am thinking about adding a line to the antivirus.exim file to not filter out any attachments, wondering if this will work.

if $message_headers: contains "abc-client.com"
then
endif

If I place this first thing in the antivirus.exim file, will this then end any filtering if the e-mail contains "abc-client.com"?

Thanks,
Andy

PS. I tried installing the CPM MailScanner per domain, but was not successful, wondering if this will take care of my problem?

 

That's not an option. Apparently, some of their clients are not technically minded and it is difficult to explain how to zip a file. I need to know how to turn off the scanner for their domain, will my suggested change work?

 

After thinking about it, would this be better:

if $message_headers: contains "abc-client.com"
then
deliver
endif

I am just trying to confirm this will work before I put it in the antivirus.exim file.

Thanks,
Andy
