hi,
here's my problem, which i think i cannot do w/in postfix.
i'm going to have to allow mail to get delivered (in principle,
not in fact) to all machines of the form
*.arlut.utexas.edu
i'm partly unable, partly unwilling to generate a relay recipient map
that contains this:
<all possible users>@<entire list of machines>.arlut.utexas.edu OK
anyway, that might allow some mail to go places i don't want it to go.
and doing the list properly isn't feasible because i just won't get
the cooperation i'd need from the users.
(office politics, ultimately. don't ask.)
is there a way to accomplish this? i can't do this (right?)
user@*.arlut.utexas.edu OK
at least, i can't find that kind of thing documented.
You can use a regexp or pcre map for wildcard subdomains.
/^user@.*\.arlut\.utexas\.edu$/ OK
If the internal servers reject unknown recipients during SMTP,
you can let postfix automatically build the user list by using
active recipient verification.
Examples are with the docs.
http://www.postfix.org/ADDRESS_VERIFICATION_README.html#recipient
It's also possible to limit the scope of the verification
probes to specific recipient domains by using a
check_recipient_access map, similar to this example (but using
the recipient, not the sender)
