and is smtp running on this server / computer ... ?

at your firewall

 

[RockChalk]

It's a "domain.com"
I told that I need to be able to do the following from my workstation:
telnet domain.com 25


So you think it's the firewall?

 

[Davetoo]

Are you on the same subnet as the mail server? or is it external from you? If it's external, probably the firewall(s) blocking access. If you're on the same subnet, make sure the SMTP service on the target server is running.

We are a single domain and we are at one site. SMTP is running. I wondering about DNS at this point.

Is your mail server set to accept anonymous connections? Not relays..connections?

[buddafish]

and you can telnet to port 25 from/on the mail server...

 

[RockChalk]

I can telnet to that port from the email server.
Does that mean I'm ok?

[buddafish]

i guess that depends on what you are attempting to do... does the email server send and receive emails right now?

It's a "domain.com"
I told that I need to be able to do the following from my workstation:
telnet domain.com 25

The proper syntax is:
telnet server_name.domain.com 25

Well duh! lol, dearingkr is correct, and we all missed it. You have to telnet to the machine name, not the domain name.

OK thanks that works if I put in the name of our email server.
I might need to post on the exchange forum but I'm having DNS problems and my out going emails are being delayed.

Our main DC is our DNS server and it's using fowarding.
Do you all know of any go links to trouble shoot this.
