Not receiving external emails
LockedBackground info:
I have a windows 2000 Active Directory Domain with service pack 3. I have one DC/DNS/EXCHANGE server. I’m running Exchange 2000 with service pack 3. I have a router with port 25 enabled for SMTP traffic. The same port is specified in Exchange as well.Problem:
I am unable to receive External email ONLY. Also, I can send to hosts outside my network, but I can’t send INTO my network. I don’t get any errors or anything saying that the message is undeliverable.
I’m not sure if DNS is the issue here, but I do have an MX record pointing to my email server, which is the 2000 server itself.
Also, one important point. This exact setup did work in the past. I since rebuilt my server, but the setup is exactly the same.
Does anyone have any suggestions?
