Here's one I thought interesting: http://www.snertsoft.com/sendmail/milter-7bit/ This Sendmail mail filter will tag or reject email with invalid message content transfer encodings as given by RFC 2045. For example a message that is declared to use MIME 7-bit encoding, but contains an 8-bit octet, NUL byte, and/or unpaired CR or LF characters, would be considered invalid and tagged/rejected. Variations of these checks are performed for MIME parts with 8-bit or binary encodings. ----- MIMEDefang already does the NUL and CR/LF checks as "suspicious character checks". But, I'm wondering if the 8-bit check would be useful. Here's another: http://www.snertsoft.com/sendmail/milter-date/ This Sendmail mail filter verifies the conformance of the date-time strings found in the Received:, Resent-Date:, and Date: headers with respect to RFC 2822 section 3.3 Date & Time Specification. The milter also checks that the date-time strings in the previously mentioned headers have coherent relationships betweeen themselves and the current mail hop. Mail can be tagged, rejected, or discarded accordingly, if the date-time strings have invalid syntax, semantics, or are incoherent. ----- How much of this does SpamAssassin do?
