A question about postmaster callout verification has been sent to me
(see the message below). I am not at all sure whether these days people
want to check for <postmaster> or not. I replied to the message as
follows:
-----------------------------------------------------------------------
That is an interesting point. It is true that the RFC does specify that
<postmaster> without a domain should always be accepted. I wonder,
however, if all the people who want the callout "postmaster" check also
want to do that check, or not? Times do change, and I'm not sure that
too many people know about <postmaster> these days.
-----------------------------------------------------------------------
What do people on this list think?
Regards,
Philip

Subject: Exim 4 postmaster verification
Hi,
I personally would like to use postmaster verification on some of the servers
that I administer but there seems to be a problem with it.
It first tries to verify the sender and then tries to verify
<postmaster@sender_domain>. But according to the RFC exim should after that try
to send to <Postmaster>.
my acl:
--- snip ---
deny message = Sender verification failed.
! sender_domains = +accept_without_postmaster
! domains = +accept_to_without_postmaster
! verify = sender/callout=10s,postmaster,defer_ok
--- snap ---
bye
Stefan
