Quite some time in the past, I created an MPEX "expression" program to
create files in Microsoft's "file-format API (FFAPI)" to load into our
ms-mail e-mail system.  Turns out this format is fairly close to the
"standard" internet e-mail format, but has a couple of extra fields [well,
TAKING things out is always EASY, right?]

I'm converting the program so it creates "internet" standard files, but I'm
running into a problem -- what to do with the SECOND message received?

Essentially, MS's format was something like this:

VERSION:3.00
FROM:<USER>
TO:<USER>
SUBJECT:<SUBJECT>
TEXT:<SIZE of message in BYTES>
[message]
VERSION:3.00   <--NEXT message begins here

Thus, a file for "import" could hold multiple messages.  My question is how,
if at all, does sendmail differentiate between multiple messages in it's
input stream?  I *thought* that a line beginning with
"From:<user@somewhere>" would indicate a new message and it would break at
that point, but this doesn't appear to be the case.

I also seem to recall a line with a single "." as a message seperator, but
trying that seems to have dropped the second and succeeding messages
entirely.

Or is it simply the case that "sendmail", as defined, ONLY sends <1> message
at a time -- multiple messages requiring multiple invocations of the program
[which seems to be "the unix way"]
