Re: Routing internet mail out through a different firewall

[Tom Kreimer <tkreimer@xxxxxxxxxxx>]

Greg, I have not done this myself, but if you want to route certain 
Internet domains to different mail hosts, you can add a domain document 
(on the config tab, under messaging, under domains) and specify a "Foreign 
SMTP Domain". You can then route *.company.com to a specific SMTP host.

Or, this could simply be a routing issue at the OS level (and this I have 
done). If you want mail for company.com to take a different "route" to the 
Internet instead of the default one, first determine where the mail goes 
(resolve the MX record for company.com) and add the network or host 
route(s) using the alternate firewall as the "next hop".

I hope that this makes some sense.

We would like to route some SMTP mail out through a different firewall 
than all of other internet mail now travels through. The Domino server is 
running in another partition on the iSeries, where we have 4 other Domino 
servers running. I have tried using the Relay Host field and the Smart 
Host field on the Server Doc, and that didn't work. I tried a Connection 
Doc and that didn't work. I am thinking that this is a network (DNS?) 
issue on the iSeries, since my simple tests didn't work. If that is the 
case, then I won't be able to use the iSeries Domino server to do this, 
since the other partitions will need to use the real outbound firewall to 
send mail to the internet.

If you have some ideas, I would appreciate it.

Thanks.
