Does the SysVr4 mailer add Content-Type: and Content-Length: headers to
the messages?
This is probably the "best" way to deal with multi-part messages as well
as multiple individual messages in a single file, but it would be nice
if someone would document it.

I have the "AT&T Unix System V Release 4.0 Migration Guide for System V
Developers" in front of me.  Under mail(1)  it says "The format of the
mailbox file has changed, and mail is changed to read the new format".
Thanks, guys.  Hope that wasn't proprietary information I just
released....
