Here is my current configuration within Exchange 2007. I have a mailbox called support@domain.com. This is forwarding to a contact which has an "external" e-mail address of support@192.168.1.50 (the IP of a workstation). The workstation has an SMTP server running on it. Our goal is to get e-mail to be delivered directly to the workstation. Of course, this isn't currently working. Here is the error I receive: support@192.168.1.50 #554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain ##rfc822;support@domain.com What can I do within Exchange to get this working?

You might could try creating a specific Send Connector for that workstation (Org Configuration -> Hub Transport -> Send Connector Tab). Basically use the computer workstation as the smarthost. Tim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

Would that affect any e-mail between internal users or external? I need to make sure I don't impact production e-mail.

ISTR that to route directly to an IP address, it needs to be in square brackets, e.g. support@[192.168.1.50] Outlook Web Access For PDA , OWA For WAP www.owa-pda.com email a@t leederbyshire d.0.t c.0.m

Exchange 2007 no longer recognizes the IP address literal form of addressing. FWIW, the correct use of an address literal requires that it be surrounded by "square brackets", e.g. x@[1.2.3.4] --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Symptom: Exchange 2007 does not accept emails with address literals in the "mail from" or "rcpt to" fields Cause: This is by design Resolution: Configure the value in the SMTP address without address literals Resources: Exchange Server 2007 and Address LiteralsJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com
