to block all outgoing attachments with amavisd you could maybe use $banned_filename_re = new_RE( [ qr'^\.[a-zA-Z0-9]*$' => 1 ], ); To allow or to block certain attachments types on a per user basis you can use a dedicated policy bank for this. Here you'll find some examples: http://www200.pair.com/mecham/spam/bypassing.html http://www.ijs.si/software/amavisd/amavisd-new-docs.html#pbanks If you use a sql database you could maybe use the field "banned_rulenames" in the table "policy". Then it's necassary that you define a set of banned rulenames for allowed and/or disallowed filetypes per user. See readme.sql-mysql: banned_rulenames varchar(64) default NULL -- comma-separated list of names mapped through %banned_rules to actual banned_filename tables Daniel ------------------------------------------------------------------------------ Come build with us!
