I improved my toaster by rejecting virus at smtp level instead of deleting
them at delivery time. I use Clamav+qmail-qfilter with this script:
---
#!/usr/bin/perl
$MKTEMP='/bin/mktemp' ;
$CLAMSCAN='/usr/local/bin/clamdscan' ;
@file = <> ;
$TMPFILE=`$MKTEMP /tmp/clamtemp.XXXXXX` ;
chomp $TMPFILE ;
open CLAM, "|$CLAMSCAN --stdout - > $TMPFILE" ;
print CLAM @file ;
close CLAM ;
open TMP1, "<$TMPFILE" ;
while ( <TMP1> ) {
if ( $_ =~ /FOUND/ ) {
close TMP ;
unlink $TMPFILE ;
exit(33);
}
}
close TMP ;
unlink $TMPFILE ;
print @file ;
---
About exit code 33 instead of 31, I changed qmail.c to reject with a
specific message: "554 rejected message because it contains a virus"
About SA, each account has anti-spam turned off by default and users can
turn it on if needed.
