How are you checking? main.cf: mime_header_checks = pcre:$config_directory/mime_headers.pcre $ cat /etc/postfix/mim_headers.pcre /^\s*Content-(Disposition|Type).*name\s*=\s*"?(.*\.(ade|adp|bas|bat|chm|cmd|com|cpl|crt|dll|exe|hlp|hta|inf|ins|isp|js|jse|lnk|mdb|mde|mdt|mdw|msc|msi|msp|mst|nws|ops|pcd|pif|prf|reg|scf|scr\??|sct|shb|shs|shm|swf|vb[esx]?|vxd|wsc|wsf|wsh))(\?=)?"?\s*(;|$)/x REJECT Attachment name "$2" may not end with ".$3" That file was last modified in 2004 (to add swf and pif, IIRC). The check nearly never hits anymore (It has not hit at all in over a week). -- Actually all I wanted to do was to put an incoming email in the hold queue. I was using, in the header check, /^Received:/ HOLD which works fine when an email comes in from an external source. If I try and inject a complete email from the Postfix server itself using sendmail -t < filename.eml it was bypassing all checks. On checking the logfile, and in the man page, it would seem the sendmail Postfix program just uses postdrop and places it straight into the outbound queue. I thought locally injected emails would have passed through the same checks. Thanks.
