Configuring internal email transfers

[wyzard]

Hello,

I have a server in my organization that is in a DMZ. It uses it's own SMTP service.

I want that server to use my Exchange server to send email.

I'm not sure how to set this up.

Can someone point me in the proper direction?

Thanks,

Wyz

What software is using the SMTP service?

You may choose that leaving this alone is a good thing. If you enable relaying for this server in your DMZ this machine could be an open relay point used for sending spam, which gets your Exchange server blacklisted.

If the server as it stands is used to relay spam, and gets blacklisted, at least your corporate mail will still be allowed (assuming your are using a different public IP address for the two servers.)

Hi,

It is just a web server that handles some transactions that has information provided by the user. Then that information needs to be sent by email to an internal address. The problem that was happening was that our Firewall saw the incoming email as a spoof and rejected the email.

I think we have resolved this issue by using some internal setting adjustments and using the Smart Host settings.

Thanks for checking in and looking at the issue.
