Only allow specific users in access or virtuser or anything
bards1888
I have a mail gateway with the latest sendmail + mimedefang +
spamassasin etc and I would like to *ONLY* recieve mail for 2 or 3 users
at my domain. That is I would like to do something like this in access;
-------------------------------------
To:sa...@mydomain.com RELAY
To:in...@mydomain.com RELAY
@mydomain.com ERROR:5.1.1:550 User does not exist on this system
-------------------------------------
I have a mailertable entry for the real final destination for the domain
and it checks for valid users etc, but I think that is too late in the
process and I'd like to reject without receiving the mail.
I've read there are many options, LDAP, milter-ahead, milter-spf etc,
but what I'd like to know is how can I do this without another bolt-on
piece of software ? Can I used virtuser or is that for local delivery only.
Any help appreciated.
Cheers.
Bards.

That's best handled in virtusertable.
postm...@mydomain.com info
ab...@mydomain.com info
sa...@mydomain.com sales
in...@mydomain.com info
@mydomain.com ERROR:5.1.1:550 User does not exist on this system
(I added two addresses that should always be there.)

You might try
To:mydomain.com ERROR:5.1.1:550 User does not exist on this system
in you access file with the other entries as you entered them. We use
that here, but we do not use mailertable or virtuser so I don't know if
they interact with access.

Make the LHS of that last line 'To:mydomain.com' instead, and use
FEATURE(`blacklist_recipients'), and you're almost there. The missing
part is that to take the user-part of the recipient address into account
for relay-allow, you need to use sendmail 8.13 and the undocumented
feature
define(`_RELAY_FULL_ADDR_', `1')
I would have given you a Google reference here, but it seems Google
Groups have been utterly destroyed. Sigh, why can't they just follow the
venerable "if it ain't broken, don't fix it"...

Would this only work for local delivery/users ?
This machine is a gateway or relay to the real mailserver for the domain
in question.

I have been using this method but it bounces back to the "spammer".
Is there a way to combine with access and use DISCARD ?
So only the required 2 or 3 aliases get thru and the rest are discarded
