Thanks, this is a good idea. I was not aware of the possibility of a
catch-all address.<br>
<br>
Also thanks to everybody that sent me ideas. I think this will work.<br>

<pre wrap="">I would google for creating a catch-all address and set the
destination of the catch-all to an alias defined in /etc/aliases
pointing to /dev/null.
You'll probably need to use virtuser table to do this.

Thanks for the idea. I'm not trying to do anything spam or virus
related. This is an internal smtp server just for internal email alerts
to internal users. I need to avoid the error message when it gets email
for an unknown user. I suppose I have to do some testing.

System users may not need to be listed, but if you are pulling them
from ldap.. then maybe. I've used this on relays, not mail hub.
Why would you want to create such a spam magnet anyway?

<pre wrap="">Hi Eduardo,
Thanks for the answer. For now I would be happy just to silently
discard mails
to users that are not linux users on the same server. But my real
problem
further down the road is in ldap (active directory). So users not in
AD are
considered invalid emails. I decided to approach this in steps ;-)

Sendmail should be doing this already... You have changed
something to make it
NOT reject unknown users.
Sendmail can "discard" the email, in fact in access.db you can
setup for
example "From: 1.2.3.4 DISCARD" so every email from that ip is
silently
discarded. How do you now if an user is either valid or not? Ldap?
