Exchange doesn't recognize internal addresses

[rzawrekta]

I've recently set up a test server running Exchange 5.5 on Windows 2000 (my boss wisely doesn't want to deal with Active Directory). I've set up most of the server, and it seems to be working fine when we receive mail to the server. However, every time that we try to send email to the internet, we get a 550 relay is prohibited message. I have set up prohibitive mesaures found on tek-tips to prevent spam relaying. However, we need to use relaying as we will be using IMAP4. We now think that the server doesn't recognize our email address as internal and is therefore blocking it. Any hints or suggestions?
Thanks a lot in advance..

You only want your LAN to relay off of your exchange 5.5. You need to setup a IP range in the routing tab restriction somewhere. Once you do that, you should be able to allow your computers on your LAN to relay off the Exchange 5.5

By the way, active directory is not that difficult.
