MailScanner + Sophos + McAfee

[Quentin Campbell]

I am running MailScanner 3.20-6 with both Sophos and McAfee A-V
software. The mailscanner.conf file says:

 Virus Scanner = sophos, mcafee
 ...
 Sweep = /usr/local/Sophos/bin/sophoswrapper,
/usr/local/uvscan/mcafeewrapper

I had assumed that if a virus was _found_ by Sophos (first in list) then
MailScanner would not bother calling McAfee. However it does and this
behaviour pre-dates 3.30-6.

Is there a reason for this?
