Hiya,
thanks for your reply’s. My solution was as easy as adding the line
“/^([<]+[>])$/ OK" to my access map.
Changing smtpd_null_access_lookup_key didn’t seem to have any effect.
Why my setup looks like this? mail-server1 servs a couple of other mail
domains, not only the one destined for the mailing lists. An access list
here would affect all domains, right? Also, by moving the access part to
the satellite server, it keeps the config on mail-server1 straight.
True as well that mailman can restrict senders to list members only but
I have a couple of open lists that should be addressable by all
participating domains/company’s, no one else.
Cheers,
Daniel

2 postfix mail server, one, mail-server1, is connected to the
internet, the second,
calling it list-server1, which serves a few mailing lists, is only
reachable thru
mail-server1.
On mail-server1 a transport map entry sends everything for
@list-dom.de to list-server1,
list-server1 does his work and sends all back to mail-server1 which
then delivers to
the final destination.
On list-server1, to prevent the whole world sending mails, I have
installed a
check_sender_access map to accept a few allowed domains, reject
everything else.
I don't understand what is actually your scenario and what exactly are
you
trying to prevent.
From what you write, I assume that only mail-server1 is open to
receive mail
from the Internet, and it forwards only messages that should reach
list-server1 to that server. I assume list-server1 does not accept
mails
directly from the Internet, so there is no possibility of "whole world
sending mails" to it. (If it isn't the case, then just block
list-server1
from receiving mails from anywhere except mail-server1 using
check_client_access).
Maybe you want the people who are not subscribed to the mailing lists
on
list-server1 to not be able to send mail to those lists? But you can do
this
directly on mailing list level, every mailing list software has
controls
that allow to specify who is able to send to the list (usually the
choice is
everyone/subscribers only/moderators only, sometimes additionally you
can
block or allow particular senders).
So please describe more clearly, what do you actually want to do.
