[comp.mail.sendmail] Multiple domain configuration

drich@dialogic.com (Dan Rich) (07/17/90)

I am in the process of reconfiguring our mail system, and I need some
help.  Originally, we had a single domain (dialogic.com), that all of
our hosts resided under.  Now, we have expanded into multiple
countries, and I need to change to multiple domain names.  However, I
want the following to occur:

1)  Any host of the form *.dialogic.co.cc (where cc is the country
    code) should be relayed to the appropriate domain server for our
    site in that country.  This will be either a direct dialup or an
    X.25 connection.

2)  Any host not fitting the above format should be relayed to the
    local domain server through a dialup connection (ie, Uunet in the
    US).

I realize that it is easy to implement #2.  All I have to do is change
the relay host for each site.  The problem lies in #1.  I know that I
could implement it by setting up my current domain server as a relay.
However, that would require mail from Japan to be relayed through New
Jersey before being sent to New Zealand.  I would rather have each
site know about all of the other Dialogic domains.

Has anyone ever tried setting something up like this before?
