Hi, My name?s Andy and I was wondering if you could give me some help I have with the Internet mail. I have two Exchange servers 5.5. The one with the mailboxes is behind the firewall and the other one has only IMC. At the external server I have reroute all incoming SMTP to the internal domain which I have declared it in a host file. Next at the internal server I have IMC installed and have declared my real domain as inbound and all mails to internal domain to be routed to the real domain name. Moreover in the Routing Restrictions I have left it empty. The problems now I have are: Open relay, I had tried to put at the Routing Restrictions my internal Lan IPs at the ?Host and Clients with these IP addresses? but then I didn?t have mail at all. The mails at the external server stay long time before they arrive at the internal server and the recipient finally. As I saw in the Queue it tries to find the recipient but it cannot find it immediately but after a lot of retries. Can I accelerate the speed of an incoming or an outgoing mail sitting in the queue besides pressing the ?Retry now ? button which in my case does not speed up anything?
