Bounced Mail - DNS Problems?

[Kevin Miller]

They look fine from here Johnny - The relivant one's are below (probably
line-wrapped beyond reason):
 
Received: from gateway.johnnystork.ca (gateway.johnnystork.ca
[207.216.240.22])
                by safir.blacknight.ie (8.13.1/8.13.1) with ESMTP id
l356Vxcv025979

Ok, maybe I have it right now. I added the following to the local hosts
file after creating an A entry for

gateway.johnnystork.ca (points to 207.216.240.22)


# Edits to /etc/hosts
192.168.1.2             int-gateway.johnnystork.ca      int-gateway
207.216.240.22          gateway.johnnystork.ca          gateway
207.216.240.22          smtp.johnnystork.ca             smtp


I then change the sendmail forwarding on the scalix server
(penguin.johnnystork.ca, 192.168.1.3) so it points to
int-gateway.johnnystork.ca.

So take a look at the headers in this reply. Do they look correct now? I
"think" so....but  am still learning about mail server configurations.

And thanks to everyone for all of your helpful suggestions

the DNS A record for

		That would work, but another option is to have two
records in DNS:    int-gateway    IN A 192.168.1.2 
		  gateway        IN A 207.216.240.22 
		and point the Scalix box to int-gateway.  You retain the
benefits of DNS 
		that way. 
		
		Yet another option is to set up bind to have multiple
views.  My 
		internal users see one list of records, external users
see another.  The 
		hostname may be the same, but the address returned by
DNS is different 
		depending on whether they're on my internal lan or the
internet...

	Ahhh very nice.  I didn't even consider that.  :)
