I have exchange server 2000 running on a internal private network linked to an outside real ip address through a router. I can send mail all day long just fine but i cannot recieve a thing. I have checked my mx records on my external dns server and my internal one and they are both fine, i can send and recieve all kinds of other traffic from that box as well, i am running a small ftp server on it as well, i have checked the ports on the firwall and it looks like it should be fine. any help would be appreciated.
ok more details on the situation. Running external network of rrcompconsult.com dns hosted by 2 external dns servers. then i have a netgear router acting as a firewall, but i have the dmz set up to point to the exchange server. I have a dns server set up internaly on the exchange server becuase it is also a dc. i have the mx records on the 2 external servers. i can send mail out of my network to anywhere but i cannot recieve anything from any host. i tested the system using my hotmail account and i did not recieve any error message back either. this one has really got me. any help would be appreciated.
