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|wsh|\{[^\}]+\})'
to
$bad_exts = ''
But you might need to modify the filter_bad_filename to allow .txt files
through. Good luck
