Oh I've been following the thread. The reason I ask the question I did,
is to lead into this one. 

How do you differentiate between say, Spamassassin, and the various
qmail- bits? are they not also "external processes" to the smtp

To be clear, how does the "thou should not involve external processess"
fit in with an MTA made up of many small bits that each do a small fraction
of the job handled by the monolithic MTAs like Sendmail or Exim?

A positive attitude may not solve all your problems,
but it will annoy enough people to make it worth the effort.
