Do you have multiple external IP addresses? If so, then simply create a new sub domain on your external DNS service, create an MX record for this subdomain pointed at your other external IP address and external email will come in directly. For your internal systems, create the sub domain on your internal DNS servers, including MX records, but use the internal IP addresses instead. If the list server is using your Windows DNS for DNS lookups, then create an MX record for your internal domain with the internal IP address of your Exchange server so that the email stays on the LAN.
If you only have a single external IP address then you will have to route both inbound and outbound email through the Exchange server. This can be done with using an SMTP Connector to relay the email. I did this for a client using Listserv last summer. I typed up the details for my web site: http://www.amset.info/exchange/smtp-sharing.asp Simon. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fyodorov, Andrey FTL Sent: 23 March 2005 19:54 To: Exchange Discussions Subject: RE: List Service On Linux, you can install the freeware Mailman. It is a list server software. In order for mail from outside to come to @listserver.dplinc.com, yes you would need to register this name with DNS. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of McCready, Robert Sent: Wednesday, March 23, 2005 11:55 AM To: Exchange Discussions Subject: List Service Greetings all. We are trying to setup a list service (like this Exchange Discussions List) at our company, but aren't sure of the best way to proceed. We have a Linux server and are trying to configure it to receive mail at @listserver.dplinc.com. Our current domain is @dplinc.com. Do we need to register @listserver.dplinc.com on the Internet? Or, is there a way to tie this into Exchange 2003? Were trying to keep it separate, since we don't want the moderators of the list server and the Exchange 2003 Admins stepping on each others toes. We'd like mail coming to @dplinc.com to hit our Exchange 2003 server and mail going to @listserver.dplinc.com to hit the Linux server. Anybody have any suggestions on the best way to proceed? Thanks.
