A "Subject:" line is just a structured text line in the message body
and MTAs (e.g., sendmail) don't do anything differently with it than
any other line in a message body. The max length is 998 "characters".

I suspect that your MUA or more likely procmail is where the
truncation is taking place. I just did:

   /bin/mailx -s"... 200+ character subject ..."

on a C6/sendmail machine and it worked fine.
