In other words, what Sieve implementations can be configured such that a
reject causes the email to be refused/not accepted during the SMTP
transaction, instead of accepted, and then bounced back to the alleged
sender (often, in the case of spam, a Joe-Job victim).  Someone just
told me that Cyrus' implementation can't do this.

Note that Cyrus's implementation is actually LMTP, which presumes an
SMTP server will be sitting right next to it, so even if a 5xx failure was
issued, a bounce would still be generated by the SMTP server.

In any case, RFC3028 specifically says that an MDN is sent back when a
reject action happens.
