Not deliberatley, however, the same phenomenon occurs when the system
cannot deliver the mail to ~/inbox because of a disc full condition.
The mail *is* bounced in that case, but there is that message about being
unable to write to the (supposedly unusued) /var/psool/mail/username.

I'm thinking of enabling that 'mailbox' for one or two users, to see
what happens.

Check with the folks on a postfix list, since procmail has ABSOLUTELY NO 
CONTROL WHATSOEVER over what your MTA decides to do when procmail 
terminates. 

Well, I would think that the 'mechanism for control' would be the
exitcodes that are returned from procmail. Presumably there is one set
that tells the MTA that delivery failed and to send a Delivery Failure
Notice, and then another set to say that the LDA failed to handle the
mail, and that the MTA should attempt delivery using its built-in
routines. The *latter* seems to be what is happening in postfix, and so I
question whether there is aproblem with the exitcodes, or a known
compatibility issue with postfix....
