SBS 2003 sending mail but not receiving

[Mclarry76]

Hey guys,
I just set up sbs 2003. I am able to send mail but not receive. I requested network solutions to change the mx record mail.domain.com to point to my public ip address on the server. I also have port 110 open on my firewall. I also did a telnet on port 25 and received a OK.
Now does the mail in the mail.domain.com have to be the name of my server? I have read literature on the web. but my situation is as above.....
thanks...

Hey Mclarry,

If you can telnet from the outside (Internet) to port 25 of the external ip of the mail server then your firewall is ok.

That is about all that you have proved though. Did you set a policy to accept mail for that domain on the server? Under Recipient policy you must define the policy it will listen out for.

From the outside can you telnet to mail.mydomain.com 25 ? THis will tell you if external DNS is working.

From the server can you resolve external addresses? If so DNS is functional anyway.


Sounds like you are pretty close...

Thanks man. However, it seems like my telnet to 25 is not working and port 25 is not opened on my firewall. Nevertheless, I am receiving email and sending like nothing is wrong. Is this awkward? Isn't 25 supposed to respond to my telnet?

Your exchange server is should respond as long as you have port 25 being forwarded to your servers internal ip address.

I'm in the same SBS Exchange 2003 boat!!! but how do you enable port 25?
I have two NIC's Private and Public (connects to a router to get to the web).
Used EIC Wizard to configure
Send Internal=OK; send External=OK
Recv Internal=OK; recv External=NOTHING!!!
Tested SMTP using telnet (port 25)=OK
Firewall disabled on both NICs
NAT enabled on Public NIC
The existing SBS2000 Exchange =OK
Setting checked against SBS2000.
The main difference is the Firewall , but as it is disabled.......................
Can anyone give me a glimmer of hope?
