Virtual smtp server

[telecomtekperson]

OK, Pardon me, but I am new to servers.

I have an application for an IP system (conferencing center) Book a conference, and it emails the conf participants. The documentation says need a relay to our smtp server (hosted 38.XXX.XXX.XXX)

If I use port 25, nothing sends. If I use port 110, I can have mail sent to my personal email (different domain name) BUt at no point can I have it send an email to anyone on our domain name. I did make an email address for the conferencing center, just in case.

Server 2003R2 service pack 1

On the desktop where the application runs, make sure nothing is blocking port 25. For example if you are running McAfee, it blocks port 25 as a means for twarthing mass email attacks....

Check firewall extentions to see if port 25 is blocked.

And of course make sure the relay configuration on your SMTP server is set up to allow relaying for your internal clients.

Windows firewall is off. I can send through port 110, which is fine. but all the mail from my domain does not go out, it sits in the badmail folder. Why would it forward to another domain, but not sned mail to its own?

From a commnd prompt on the workstation, what happens when you do the following command:
telnet <servername> 25

FYI: port 110 is used for POP3 protocal not SMTP protocal. So it is possible that you have pop enabled and SMTP not enabled.

You didn't mention what kind of server you're sending to. If it's Exchange, relaying is disabled (usually). Make sure that you're sending TO an address that Exchange is responsible for.

Sorry fr the delay.

Problem is. I have a virtual smtp server set up. At the same time it set up a pop 3 server. Do I need to delete the POP3?

On the Virtual SMTP It is set to forward mail to a smart host.

I can get email sent to my personal email (charter.net), but I can not get the email to send to my domain (xyz.com).

Whenever the program tries to send email, i get the personal email, but everything else goes into the "badmail" folder.

Wondering if you need to put an MX record in your local dns server telling it to keep that mail local. I had a simular problem with a 3rd party server and mailing to our domain. the local MX record fixed it.
