dear all,i was told that this postmaster is a field in Server Document. But i couldn’t find any there. Can anyone tell me where is it & what is it for? Thanks.

Subject: Where is the Postmaster
Absent a named Postmaster in the PAB (either a user, group, mail-in database or the like), AND assuming that you do not have the SMTP Inbound Control “Verify that local domain recipients exist in the Domino Directory:” set to “enabled”, then…
The postmaster is the administrator (or administrators) of the server in question (server document, administration tab).
What it is for - look at RFC2822 and a few others:
http://www.faqs.org/rfcs/rfc2822.html
Basically, any host that accepts SMTP mail must accept mail addressed to postmaster@FQHN (and postmaster@[domain.literal] though this is very often overlooked).
In R6, Lotus kindly changed the behaviour of the system so that when there is no explicit postmaster, one can be inferred from the server administrator. A very sensible move if you ask me though unfortunately completely defeated by “Verify that local domain recipients exist in the Domino Directory:”. Hey ho.

Hey Chris
You said

Why do you think that?
Subject: RE: Where is the Postmaster
Because I tried it (it came up in an earlier thread here which I do not have the time to seek out right now).
I think defaulting postmaster@ to the named administrator(s) of a Domino server running the SMTP listener (in the absence of an explicit postmaster) is a brilliant idea. You have no idea how many Domino shops run without the RFC required postmaster@ because no-one thought to create a simple mail-in or alias or group or something. ND6 does this for abuse@ too.
So I decided to test it and deleted any explicit references to abuse@ (used to be a mail-in) in our PAB, then sent in an email to abuse@mydomain.
Imagine my irritation when it bounced with 550 no such user because we have “Verify that local domain recipients exist in the Domino Directory:” enabled.
And no, I do not intend to disable that setting.
It keeps mail.box from filling up with dead non-delivery reports where some brain dead ISP has their MTAs set up to reject on MAIL FROM:<> (don’t even get me started on DSN abuse).
Later.
