Basic principle: Postfix sends only the SMTP commands and message content that Postfix has not rejected. The exception is the "unknown command" event in the Milter protocol. This prevents that Postfix and Milter get out of step, for example when Postfix rejects something and the Milter accepts it. Both Postfix and Milters (or the libmilter library) have ideas of what to expect next, and I control only the Postfix expectations. Changing this on the Postfix side after almost 20 years is risky. There must be Milters that have only talked to Postfix. Wietse ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org

So I guess there is no way for a milter/policy server to know about rejected recipients (other than parsing log file)? e.g. the DCC milter would report total count of recipients (including rejected/non-existing) to DCC servers. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.

The Postfix SMTP server counts only the recipients that it accepts, not the ones that it rejects. That is, a DATA or BDAT command after all recipients are rejected will result in a "554 5.5.1 Error: no valid recipients".

Note that if you want the actual recipient addresses, (not just a count), you'll need to also intercept recipient restrictions. The Postfix smtpd(8) server does not keep the recipient list in memory, the list is streamed out into the queue file (really cleanup service or pre-queue proxy filter). -- Viktor. ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
