It would be nice if you specified how your mail is incorperated.
Was it inc? slocal?
If it was slocal, what line in your .maildelivery actually processed the
mail?

Anyway, I am assuming that you are using slocal's file (>) action to
store your mail.  Apparently, the mail being filed is not separated with
the required "\n\nFrom" which is used by BSD Mail as a message separator,
but instead it is separated with a "\nFrom".  When a mail is "filed", the
following patch will prepend a "\n" to the message to ensure that it is
correctly separated.  It has been tested on SunOS 4.0.3, SunOS 4.1, and
Ultrix 4.1.

There is another patch that was posted that fixes a couple other problems
as well as this, but when I applied it and recompiled slocal, for some reason
BSD Mail could not use the maildrop.
