Postfix header checks is my friend: header_checks = pcre:/etc/postfix/header_checks mime_header_checks = $header_checks The file /etc/postfix/header_checks contains (amongst other filtering rules) the following group of lines (white space IS important here): /^\s*Content-(Disposition|Type).*name\s*=\s*"?(.+\.( 386|ba[st]|bin|c[ho]m|cmd|cpl|dll|drv|exe|hlp|hta| in[fis]|isp|js|jse|lnk|ms[cipt]|ocx|pif|reg|sc[rt]| sh[bs]|sys|url|vb|vb[es]|vxd|ws[cfh]))"?\s*$/ REJECT Attachment file type not allowed ("$2" has the extension ".$3") This will block (almost) all e-mail with (Windows) executable attachments. Best regards, Arjen PS I read this mailinglist too, so there is absolutely no reason to CC me as well. In fact, I usually ignore traffic to this address NOT from the mailinglist server.
