  Ah, yes - I am aware of what Amavis -is-.  I was merely curious -how-
 it was telling Cyrus what folder to save the incoming message
 into.  :-)

  Well, SpamAssassin.  To be more precise:  Exim pipes the message
 through the "spamc" binary as a "transport_filter" just before it sends
 it on to the Cyrus using LMTP.  "spamc" classifies the message arriving
 on stdin, adds some headers, then finally dumps the result on stdout.

  With my patch applied, does too!  ;-)

  Aha!  That is the answer I was looking for.  Thanks (applies to you
 too, Earl R Shannon)!  I will see if I can make use of this
