I use dccproc with obtuse smtpd (before procmail is even involved).
Currently, all I can do is a discard after the item is accepted (smtpd's
shortcoming, not any of the DCC tools).

I've asked someone who has been extending smtpd/smtpfwdd (see
sd.inodes.org) to allow an external process to be called at the end of
DATA, before a 250 is issued, and accept/reject the item based on the
return code the external process exits with.

It would be nice if dccproc could return a exit code of '0' for "this
item is ok", and a '1' for "this item exceeds set thresholds".  If
dccproc had that feature, it would make things _slightly_ easier for me,
but I can certainly script around it without much trouble.
