Hi,
Are there someone out there in courier-land who won't mind sharing some
experiences with virus scanning with courier?
I've been playing around with amavisd-new and ClamAV some time now and have
not been able to get it to run to my satisfaction.
What I want to do is to scan every mail (local & SMTP) that hits my server and
only put in X-headers (X-Virus-Scanned: & X-Amavis-Alert:) with the status of
the message - NO quarantine is needed.
So if someone has a cookbook for this type of setup I would be grateful if you
didn't mind to share it.
I don't use amavis, just a simple script that can be used as an xfilter:
/etc/courier/maildroprc:
xfilter "/usr/local/sbin/scanmail"
/usr/local/sbin/scanmail:
#!/usr/bin/perl -w
use strict;
mkdir "/tmp/mailscan", 0777;
umask 077;
my $tmpnam = "/tmp/mailscan/$$";
my $fh;
open $fh, ">$tmpnam" or do {
`logger -t scanmail "cannot open $tmpnam"`;
exit 1; # not much we can do, defer all mail
};
my @lines = <>;
print $fh @lines;
close $fh;
my @result = `/usr/bin/clamdscan --disable-summary --stdout $tmpnam`;
my $rc=($?>>8);
unlink $tmpnam or `logger -t scanmail "cannot unlink $tmpnam"`;
my @extra_headers=("X-Scanned: Yup\n");
#print "rc=$rc\n", @result;
map { s/^ *//; push @extra_headers, "X-Virus: $_\n"; } grep /FOUND/,
@result;
my $headers=1;
for my $line (@lines) {
if ($headers and $line eq "\n") {
for (@extra_headers) {
print;
}
$headers=0;
}
print $line;
}
exit 0;
