There is another method, which is currently used on the IETF mailing lists with a public archive. First, the current statement does point you at the older statement: <http://www.ietf.org/IESG/STATEMENTS/mail-submit-policy.txt> Which says this: In other cases, it MUST be possible for the sender of a legitimate message, whether a mailing list subscriber or not, to determine if it is has been dropped as apparent spam. This can be done in several ways; all of these have their advantages and disadvantages. b. Provide an up-to-date archive of accepted postings. Unfortunately, while this can show dropped messages, it doesn't help if the email is merely delayed, nor does it say why a message was dropped. This MAY be used. This is the method currently employed on IETF lists with a public archive. Thus, the onus is on the originator of a message to make sure it was distributed. I'll also note for completeness that the IETF does not reject messages after they have been accepted for delivery by the SMTP server. Messages may be rejected by the SMTP server, in which case the originator should get a notice. After that point the message is either delivered or, in the case of lists with public archives, it may be dropped.
