Spammers often change the Content-Type to image/jpg, which most MUA's will render fine even though it is wrong. I have this in my local rules: mimeheader __ANY_IMAGE_ATTACH Content-Type =~ /image\/(?:gif|jpe?g| png)/ mimeheader MIME_IMAGE_JPG Content-Type =~ /image\/jpg/ describe MIME_IMAGE_JPG contains wrong MIME type image\/jpg score MIME_IMAGE_JPG 1.0 662 hits on MIME_IMAGE_JPG this week, and no complaints about the flag images. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281, CNX www.austinenergy.com
