Wow, how did you ever know to use it?

Not exactly.

_if_ you have the sendmail mts configured (see mts.conf) then what will
happen is sendmail gets invoked with the following flags:

        -bs -oem -om -ov

(The key one here is -bs).  That invokes sendmail in the "standalone"
SMTP mode and post then talks SMTP to it.  spost runs sendmail -t and
just outputs the draft message to it.

The big difference is you don't need a From: line when doing sendmail -t;
you need one when doing SMTP (either talking to a remote server or via
sendmail -bs).  It's not clear to me what the envelope from header is set
to when you're doing sendmail -bs.
