Almost there (was Re: BSDI-4.0 MX to Dedicated ISDN client)

[Tim Williams]

I believe I have this mx thing licked, but I still have one setting to tweak (I
think).

I have created "mx3" and it is set to send mail to the remote mail server at ip
.100
This is what the db file looks like. It is working perfectly now with mail sent
internally.
However, it is giving a "relaying denied" message back to anyone sending mail
from outside
my network.

IN NS ns1.domain.com.
IN NS ns2.domain.com.

IN MX 05 mx3.domain.com.
IN MX 10 mx2.domain.com.

IN A 211.111.111.1
www IN A 211.111.111.1
mail IN CNAME mx3
<END>

mx3 is setup to point to foo.com at 211.111.111.100

The place I need help is in the /etc/sendmail.cf file where it says to put the
hosts that we allow relaying for.
This is the default setting.

# MX map (to allow relaying to hosts that we MX for)
Kmxserved bestmx -z: -T<TEMP>

Can anyone help me out with how to set this?

Thanks again,
Tim
