Sounds like a new "feature" designed to force people to use MIME. > The last line of the messages contain non printable characters > along with the contents of the Subject: line. Sounds like the trailing subject on a PROFS note. If so, the problem is presumably in the translator that converted the PROFS note into RFC822 mail. It should strip out the trailing subject and leave only the one in the mail header. John
