I was updating file type definitions in my header checks when I noticed I have header checks as well as mime header checks :
/etc/postfix/main.cf header_checks = pcre:/etc/postfix/header_checks.pcre mime_header_checks = pcre:$config_directory/mime_headers.pcre header_checks has (now updated) "/^Content-(Disposition|Type)...." AND lots of old rules from Jim Seymor's page and securitysage page and stuff from the ml; mime_header_checks has just "/^Content-(Disposition|Type)...." AND nothing else do I need both ? do I need "/^Content-(Disposition|Type)...." in both checks ? thanks for any pointers, V > Try the updated rule in http://www.postfix.org/header_checks.5.html. > This fixes the problem.
