>maraboli@disca.utfsm.cl
>maraboli@ociv.utfsm.cl
>maraboli@ind.utfsm.cl

>How can I solve this Slight mess ??
This was not understood at first, but was made with a few emails..
The answers were that:
- use any sendmail and get some patches available (tricks with the Rulesets).
- you can't
- use the new Sendmail 8.8 with "virtusertable" feature.
Since Sendmail 8.8 incorporated this feature it was not necessary to
look at old patches.
The virtusertable has to look like this..
user1@ind.utfsm.cl user1
user2@ind.utfsm.cl user2
@ind.utfsm.cl unknown
user3@ociv.utfsm.cl user3
user4@ociv.utfsm.cl user4
@ociv.utfsm.cl unknown
maraboli@disca.utfsm.cl maraboli
@disca.utfsm.cl unknown
This way ONLY user1 and user2 will RECEIVE mail as belonging to
the ind.utfsm.cl domain, and user3 and user4 willl ONLY receive mail
as belonging to ociv.utfsm.cl domain...etc.
any other user in the @ind.utfsm.cl domain will be unknown.
You have to use this table with DBM or NDBM...
I have not tested this yet, i AM in the process of configuring a standalone
machine to do the test...don't want to mess the mailserver !!
Thanks for all your help..
