This e-mail is a presentation of an idea for comments prior to drafting the idea into a formal request for comments document. The idea presented herein is within the realm of e-mail practice and is therefore on-topic for the anti-spam research group, although the idea would not directly reduce spam, as the idea if put into wide practice would simplify the operation of large mailing lists on both the sending and receiving end. The idea if implemented would ease content-based filtering at the server as messages to multiple recipients would no longer require separate complete transactions for each recipient when sending to servers that implement complex per-recipient acceptance policies. The idea is a new ESMTP extension. The new ESMTP extension is tentatively called "DATAFIRST" When a server identifies itself as supporting the DATAFIRST extension, the SMTP transaction may be re-ordered from MAIL FROM, RCPT TO, DATA to MAIL FROM, DATA, RCPT TO with the full range of acceptance/delivery status response codes available at RCPT TO time rather than at the end of the DATA command. -- David L Nicol _______________________________________________ Asrg mailing list Asrg@ietf.org https://www1.ietf.org/mailman/listinfo/asrg
