[Mimedefang] md 2.7 works w/ file::scan

[Douglas J Hunley]

Just thought I'd let everyone know that integrating file::scan is fairly 
simple with 2.7
My mimedefang-filter looks like:
sub filter_begin {
...
my($code, $category, $action) = message_contains_virus_filescan();
if ($category eq "virus") {
action_quarantine_entire_message();
action_bounc("Message appears to contain a virus, rejected");
}
...
}

I tested it with a fake EICAR virus, and sure enough it got bounced back with 
the above error!

Good job!
