I haveExch Svr 03 SP2 running on a Win2k3 std svr. I recently had a server crash and I took the domain down and then built back from the ground up. The issue is that I cannot receive email now on my exchange server. I have run net diag and all is successful. I have the mx records properly setup in DNS with the appropriate PTR record. I am able to ping the server from the outside to port 25. I can send email to an outside address without issue. OWA and OMA work fine. (Active Sync with my Iphone works without issue) I have run the setup wizard under the exchange server and it tells me all is well. Where can I go from here?Thanks!

Can you telnet to port 25 from the outside?XFOR: Telnet to Port 25 to Test SMTP Communicationhttp://support.microsoft.com/kb/153119

I get the following when Iuse xfor. I do not think that it is giving me the proper response set q=mxentprise1erver: enterprise1.enterpriseitco.comddress: 192.168.1.30 nterpriseitco.com primary name server = enterprise1.enterpriseitco.com responsible mail addr = hostmaster serial = 76 refresh = 900 (15 mins) retry = 600 (10 mins) expire = 86400 (1 day) default TTL = 900 (15 mins)

The issue is that I am unable to Telnet into port 25 on the server directly. SMTP and IIS services say that they are functioning on the server.

So you can telnet to port 25 from the inside, but not from outside your network? You posted the result of an NSLOOKUP earlier, not an SMTP conversation.

I cannot ping to port 25 on the inside

Hi,I am confused why you could telnet 25 port from the outside but not available inside.Did you try to telnet 25 port of the Exchange server from the other internal clients?Please try to send the test email by using telnet command.ThanksAllen

I am unable to telnet from the host machine or from another machine within the domain. I have fixed my DNS issue but I am unable to receive.

Hi,Please try to send the email to your internal recipient by using telnet command from outside, what's the result?And whether any error message come up in the event log?ThanksAllen
