I think maybe you want to pass only text parts, so this would do it:
-----
sub filter {
my($entity, $fname, $ext, $type) = @_;
if ($type !~ /text/) {
action_replace_with_warning('This part has been removed');
}
}
-----
But as I said a while ago, it depends exactly on what you mean by
attachment. The above assumes that text/plain and text/html are
good and everything else is not.
Note: Your choice of words as to 'This part has been removed'.

Any other ideas??
I tested using the original bad_exts value in the original
mimedefang-filter and it indeed blocked the attachments with the
extensions listed in the file. When I changed it to $bad_exts = '' as
suggested previously, all attachments came through with none being
blocked.
I am on a network that must meet some pretty stringent security
requirements and I have been told that in order to have SMTP running, I
can't let ANY attachments through (of any type or extension).
Any thoughts?

I apologize in advance as I am an extreme mimdefang newbie that has
installed the product for one purpose, to block ALL attachments from
going through the SMTP server. I see the ability to list specific file
extensions to block but that isnt what I am looking for. I want to
block ALL attachments in emails. Can someone provide specific details
as to what needs to be changed and where in the appropriate config
files. I am forever appreciative of any help that can be provided.
Untested but I think you could focus on filter_multipart in the example
and other than HTML & TXT multiparts, just return action_bounce($reply,
$code, $dsn).
This might be achieved by changing the bad_exts from $bad_exts =
'(ade|adp|app|asd|asf|asx|bas|bat|chm|cmd|com|cpl|crt|dll|exe|fxp|hlp|hta
|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|wsc|wsf|ws
h|\{[^\}]+\})' to
$bad_exts = ''
But you might need to modify the filter_bad_filename to allow .txt files
through. Good luck
