[Linux-users] Sendmail upgrade

[Stuart Biggerstaff]

In one of those "make a bunch of changes to a server then quit"
situations, we have a server in our DMZ that is supposed to be sending
mail to our regular mailserver inside the LAN, but isn't after an OS
upgrade from an older RHEL to CentOS 5.0.  If I add my desktop's VLAN to
Relay Domains, I can bounce mail from there to the mailserver with SMTP,
but mail originating on the server itself isn't leaving.  I suspect we
have run afoul a default restriction in a newer version of Sendmail or
one that is a recent default instituted by Redhat.  We've been looking
through documentation and searching the web, but so far nothing has
helped--so I'm thinking we are missing something basic.

Anyone have a suggestion for the first or second things to look at?
