Andy, Maybe this will help: Work with TCP/IP Interfaces: 172.16.0.1 255.255.0.0 ETHLIN01 *ELAN 172.16.0.2 255.255.0.0 ETHLIN03 *ELAN Work with TCP/IP Host Table Entries: 172.16.0.1 mybusiness1.com mybusiness2.com 172.16.0.2 mybusiness3.com In the above instance email forwarding works (to a test hotmail account I have) for mybusiness1.com and mybusiness2.com, but not mybusiness3.com. Below email forwarding works for all three. Work with TCP/IP Host Table Entries: 172.16.0.1 mybusiness1.com mybusiness2.com mybusiness3.com The catch is I have Qwest pointing mybusiness3.com to 172.16.0.2. (the same as mybusiness1.com and mybusiness2.com is pointing to 172.16.0.1). So, an internal message will forward to the test account, but external email sent to mybusines3.com will not resolve to 172.16.0.1. I could make the switch through Qwest but I will be hosting mybusiness4 and 5 soon and the host table only allows you to have four host names per internet address. Oh, and yes both physical lines are in the same switch. Kyle -----Original Message----- I took the liberty of re-reading your post and have a few questions. At first glance, it looks as though you have a routing issue, not something specifically related to email. Forwarding should be to an IP address, independent of physical hardware. I don't think it should matter whether you put all you IP addresses on one port (Ethernet lines) or multiple ports. Unless these ports are physically plugged into different subnets in which case you will need to route between the subnets. You reference Ethernet lines as hosting domains. I am assuming that you have assigned different IP interfaces (addresses) to these interfaces. When you moved mybusiness3.com to ETHLIN01, did you just move the IP interface from ETHLIN03 to ETHLIN01? Can you define what you did Are both physical ports connected to the same hub/switch? What are the IP addresses for the various domains? Can you define what you did in terms of IP definitions?
