[Mimedefang] Help with removing files with names defined in bad_exts
I would like to remove certain named zip files from emails but I don't wan't to discard all zip files since we use them. I tried to add the whole filename to bad_exts but this does not work. Is there somewhere else in the filter I can add this or do I need to add my own code to the re_match function.

You need to add your own code. Here's a sample (untested)
sub filter_bad_filename ($) {
my($entity) = @_;
my($bad_exts, $re);
my @badfilenames =
( price.zip,
the-price.zip,
snowhite.scr,
)
for my $badfilename (@badfilenames)
{if (lc $badfilename eq $entity)
{return 1;
}
}
# Bad extensions
$bad_exts = '(ade|adp|app|asd|asf|asx|bas|bat|chm|cmd|com|cpl|crt|dl
l|exe|fxp|hlp|hta|html?|hto|inf|ini|ins|isp|jse?|lib|lnk|mdb|mde|msc|msi
|msp|mst
|ocx|pcd|pif|prg|reg|scr|sct|sh|shb|shs|sys|url|vb|vbe|vbs|vcs|vxd|wmd|w
ms|wmz|w
sc|wsf|wsh|\{[^\}]+\})';
# Do not allow:
# - CLSIDs {foobarbaz}
# - bad extensions (possibly with trailing dots) at end or
# followed by non-alphanum
$re = '\.' . $bad_exts . '\.*([^-A-Za-z0-9_.,]|$)';
return re_match($entity, $re);
}

Should be

Sorry for repeated postings. Now that I've read the mimedefang.pl,
here's a better chunk of code:
sub filter_bad_filename ($) {
my($entity) = @_;
my($bad_exts, $re);
my @badfilepats =
(^price\.zip$,
^the-price\.zip$,
^snowhite.scr$,
);
for my $badfilepat (@badfilepats)
{if (re_match($entity, $badfilepat))
{return 1;
}
}
# Bad extensions
$bad_exts =
'(ade|adp|app|asd|asf|asx|bas|bat|chm|cmd|com|cpl|crt|dll|exe|fxp|hlp|ht
a|html?|hto|inf|ini|ins|isp|jse?|lib|lnk|mdb|mde|msc|msi|msp|mst|ocx|pcd
|pif|prg|reg|scr|sct|sh|shb|shs|sys|url|vb|vbe|vbs|vcs|vxd|wmd|wms|wmz|w
sc|wsf|wsh|\{[^\}]+\})';
# Do not allow:
# - CLSIDs {foobarbaz}
# - bad extensions (possibly with trailing dots) at end or
# followed by non-alphanum
$re = '\.' . $bad_exts . '\.*([^-A-Za-z0-9_.,]|$)';
return re_match($entity, $re);
}
