Hi,
We have an Alpha 2000/300 running Digital Unix 3.0
We have just gone into Enhanced Security mode running secsetup.
Everything is ok but sendmail. Our system does not receive any mail from
outside our domain.
A user unknown error message is returned, and the user does exist. (Believe
me). :-)
The mail returned on the source (outside domain) system is:
>From MAILER-DAEMON Tue May 28 15:31 MET 1996

------------------8<-------------------- 8<----------------------
Our DNS configuration is as follows: (genio is no routed)
genio IN A 138.100.56.26
IN MX 10 genio.eui.upm.es.
IN MX 20 fenix.eui.upm.es.
------------------8<-------------------- 8<----------------------
If I turn Security mode to BASE, everything is ok again.
Any help will be appreciated
TIA
