Sendmail wouldn't have to do all that!  It would simply have to go through its
queuefiles, looking at the envelope of each letter and determine which ones go
to the host on the other end of the SMTP connection.  The routines to do this
are, of course, already part of sendmail.  You just have to be familiar enough
with sendmail internals to tie SMTP-receiver and the SMTP-sender code
together.
