That's a great idea! I tried it but no matter what I do, sendmail is
letting everything through. Virtusertable is configured correctly in
sendmail.mc, also did the appropriate makemap. I think something has
changed in sendmail (I have 8.13.8). I've searched the world over 10
times and tried many different combinations in virtusertable &
mailertable and no matter what it relays everything. I know it is
looking at the virtusertable because sendmail lets me know if I put an
error in the file. The closest I can come is to use the access table
in a similar fashion. That does work but I can't find a way NOT to
send a reject message. That's one thing I don't want to do is to tie
up my server sending 10,000 rejects to a zombie somewhere. If I use
the DISCARD command, then it tosses the whole email and nobody gets
it, even valid users.
Is there some trick to making your suggestion work?
In my case the MX server relaying in from the internet is not itself
the delivery host. It has the domains it receives for listed in
local-host-names and the actual delivery destination is mapped in
mailertable like:
domain.com esmtp:[host.domain.com]
(the []'s let you go to a name with an A record or an IP instead of
the default MX lookup)
mailertable is *NOT* consulted for domains listed in list of local email
domains ($=w, local-host-names).
Hmmm, I guess my virtuser table maps u...@domain to [email protected] and
it is actually the host.domain mailertable entries that work - or they
work without special lookups.
Maybe you don't have the domain listed in local-host-names so sendmail
thinks it must relay. Virtual users and aliases are only checked for
the domains it process as local - but you can still relay for
delivery.
virtusertable is consulted for local email domains ($=w) and
(non local) domains listed in $={VirtHost}.
Read carefully about side effects before using macros porviced by
sendmail.org for filling $={VirtHost}.
You can fill $={VirtHost} "directly":
LOCAL_CONFIG
C{VirtHost}example.net
P.S.
The topic has been discussed a few times plus in news:comp.mail.sendmail
Search for the threads with _VIRTUSER_STOP_ONE_LEVEL_RECURSION_
[it marks one recipe but you will find references to other by the way]
I set everything up with the macros in sendmail.mc on a CentOS system.
I used to use MAIL_HUB for what I considered the 'main' domain with
mimedefang validating the recipients via smtp, but a virtuser table
lookup is much faster (at the expense of having to maintain the mapping
table).
