How can I create an internal SMTP Relay for my intranet websites, sharepoint, and other apps to use?

How can I create an internal SMTP Relay for my intranet websites, sharepoint, and other apps to use?  Currently have Exchange 2003 and it's not an open relay anymore.  Once I closed the relaying all internal websites, sharepoint, and other apps stopped sending mail.  How can I create an open internal SMTP relay?

Make sure you don't have a firewall/IDS/antivirus or other security software that may be blocking port 25 activity on the smtp server and/or the servers trying to send mail.

dont use ms exchange... setup a linux mailserver running "postfix".  in the .conf file, enable open_relay.  

then point the internal websites, share point and other apps to this linux box.  

you can send mail from the linux box, almost out of the box...  receiving is a little more of an issue, if you want to receive on that box, because then you have to setup the mx records, etc...

In exchange (Exchange 2000) go to your default smtp server > right click > select properties > Access tab > click relay button.

On the relay restrcitions dialog box, add the ip addresses of the servers you want to allow relaying from.


I know you mentioned Exchange 2003 so the instructions may vary somewhat but it's the same concept and this should do it for you.

An alternative that may also work is an IIS virtual smtp server.

Hope this helps.

Have tried both of those options with no success.  It's odd that logically it should just work but for some reason it's not.

Install IIS on another server and add a Virtual SMTP Server to it. Use that server to send internal stuff.

I have tried that option as well but the applications say they are unable to connect to that SMTP server

Tried the Linux option as well figured I would fall back on a stable O/S with vanilla Sendmail nothing worked with Linux either

can you sendmail from the linux box directly?  if so, copy and paste the conf file here...

The firewall was only allow a single IP address to send and receive.  Change the port numbers for the apps to another like 2525 and told the firewall to accept the meeasges then connected and sent.  LOL now I just need to find out where they went because they didn't arrive at the address sent to LOL

After following the instructions from capttjjt, have you tried restarting Exchange services?

This should do the trick.
