My apologies to anyone looking at this in the archives and wondering
why I seem to be responding to a non-existent email. Howard didn't
feel that his email was worth archiving, even thous the replies are
going to be archived.

I have a Linux/Postfix server that accepts email from the Internet,
performs filtering checks on the email and then forwards acceptable
emails onto a Linux/Domino server on the local intranet.
The Postfix checks are all being done by LDAP so I am able to see what
is happening on the Linux/Postfix server.
Postfix has the relayhost parameter set in main.cf to point to the
Linux/Domino server so that emails are correctly forwarded on.
I can see the Linux/Postfix server doing all the checks that I have
specified in main.cf. These include:
However, the smtpd_recipient_restrictions appear to be failing safe with
a default DUNNO result rather than a default REJECT result. The same
checks, when not used in conjunction with a relayhost setting appear to
default fail as REJECT rather than DUNNO.
Am I right in assuming that the use of the relayhost parameter is
causing this change in default behaviour, and how is the best way to fix it?
The Domino machine, being the real MTA, obviously knows what addresses
it's going to accept mail for (the ones that are defined as valid
addresses) and which it's going to reject (the rest - unless it has a
catchall, in which case, there aren't any that it will reject).
Does the Postfix machine have some way of knowing this same
information, or is it just left knowing that "all mail for that domain
gets forwarded to 220.127.116.11"?
There is nothing more worthy of contempt than a man who quotes himself
