Hello, folks. Please review and provide feedback on the "refuse"
extension, designed to mostly replace Sieve's "reject" command.
It's been accepted as an I-D (-00), but we've made some further changes
to what's published, so please review and comment on what's at
<http://www.elvey.com/it/sieve/draft-elvey-refuse-sieve-01h.txt>
We welcome feedback, particularly
- changes that include replacement text or
- suggestions from Sieve implementers.
Abstract
With "refuse", Sieve gains the ability to simply not accept an
email during the SMTP transaction (instead of accepting it and then
sending an MDN [MDN] back to the alleged sender using "reject").
A Joe-job is a spam run forged to appear as though it came from an
innocent party, who is then generally flooded by the bounces, MDNs
and messages with complaints. With "reject", MDNs contribute to
the flood of Joe-job spam to victims of Joe-jobs; SMTP level
refusals usually don't. So "refuse" provides users the latter
method to handle unwanted email.
The further changes were limited to Section 13 'Open Issues for
Discussion' and a typo.
