<With this config, if [EMAIL PROTECTED] sends a message to [EMAIL PROTECTED], the message gets sent out of the abc.com mail server, gets delivered to the xyz.com mail server, and then gets forwarded back to the abc.com mail server for final delivery>
First, configure all clients to use xyz.com as their outgoing smtp server. that should get rid of the loop problem. I would also create new accounts on xyz, and forward all [EMAIL PROTECTED] mail to [EMAIL PROTECTED] later, you can create a virtual abc.com domain on xyz.com, and change the MX DNS for abc.com, and localy forward mail for [EMAIL PROTECTED] to [EMAIL PROTECTED] Finally, after a few days, shutdown the original abc.com mail server ---------- Original Message ---------------------------------- From: "Chris McFarling" <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] Date: Thu, 20 Dec 2001 15:52:32 -0800 >I have a situation where I need to set up a one-way peer from my IMail >server to a Netscape Messaging Server.

This definitely works, but the >xyz.com admin wants to get rid of this loop.

This works if the destination username is one of >the 5 accounts on the abc.com server.

The problem with this is when joe sends to >[EMAIL PROTECTED] Since there is no bill account on the abc.com mail server, >When joe hits the send button he gets the following error: '550 unknown user ><[EMAIL PROTECTED]>'.

To try it out, I added the IP address of the xyz.com >mail server to the peer list on the abc.com server. I added the correct >entry to the hosts file as well.
