SpamAssassin Rule: SUBJ_ILLEGAL_CHARS

Standard description: Subject: has too many raw illegal characters

Explanation

The Subject header contains 8-bit and other illegal characters that should be MIME encoded, as described in RFC 2045

This suggests that the sender is using badly-written mailout software, rather than a regular email program.
