dovecot - Apr 2010 - sieve plugin - reject sends MDN. Can it 550 reject ?

I'm using dovecot-1.2-sieve-0.1.15 with dovecot-1.2.11.

I have a reject test filter that looks like this:

require "reject";
if header :contains "subject" "reject" {
reject "bye";
}

Is there any way to get a "reject" filter to send back a 550 reject as
detailed in http://ietfreport.isoc.org/idref/rfc5429/#section-2.5 rather 
than a MDN?

The MDN can result in blowback spam. :-(

Thanks,
Ken

Only the MTA can do that. By the time dovecot gets the message it has already
been accepted, and it is too late for a reject. You could try a milter that
runs in front of your mailserver and can reject a message during the data
phase. Once accepted, and the connection is closed, there is no way to do what
you ask.
