This memo updates the definition of the Sieve mail filtering language
"reject" extension, originally defined in RFC 3028.
A "Joe-job" is a spam run forged to appear as though it came from an
innocent party, who is then generally flooded by automated bounces,
Message Disposition Notifications (MDNs), and personal messages with
complaints. The original Sieve "reject" action defined in RFC 3028
required use of MDNs for rejecting messages, thus contributing to the
flood of Joe-job spam to victims of Joe-jobs.
This memo updates the definition of the "reject" action to allow
messages to be refused during the SMTP transaction, and defines the
"ereject" action to require messages to be refused during the SMTP
transaction, if possible.
The "ereject" action is intended to replace the "reject" action
wherever possible. The "ereject" action is similar to "reject", but
will always favor protocol-level message rejection. [STANDARDS TRACK]
