Where did you see it? It is not in the distribution I believe. > I mean... I suppose that if an email > have a bad header is a bad email (or at least a bad structured email).

Because is is mostly harmless as far as security is concerned, and it does not contribute to spam blocking, which SA can take care of by itself quite well. > Exist lot of emails that have bad headers and are good email? There are some types of errors that are rather frequent, mostly due to poor quality of mail clients, or misconfigurations. Some of the more frequent ones are: - MUA does not properly encode 8-bit national characters according to RFC2822 / RFC 2047; this is specially common with web-based mailers or with very old versions of mail readers, or with clueless users who misconfigure their clients; - some MUAs (like Eudora, or some mailing list) supply double Message-ID header field; - some MUAs (like IncrediMail) don't know how to properly fold long header fields, leaving empty lines in a header; - soma MUAs or mailing lists supply multiple To: header fields; - bounce messages often contain truncated sections of original body, chopped with no regard to repairing MIME structure; > Can anyone point me to a link that explain this issues? RFC2822. Don't have a better one at hand. Mark ------------------------------------------------------------------------- Take Surveys. Earn Cash.
