Topic: Perimeter email server

[Librarian]

Good morning

Hope somebody can give me a few pointers.

I want to setup our SME Server to act as a perimeter email server. This means that the SME server sits in the DMZ, and receives mail from the outside world first, scans for viruses and spam mail before forwarding it to an internal email server outside the DMZ. I have already installed Spam filtering as well as ClamAV antivirus.

I assume that I have to fill in the "Delegate Mail Server" field to have SME Server forwarding all mails to the internal mail server. Am I correct? Will this allow SME to first scan all incoming mail for spam and virii before forwarding it? Do I need to add users to the users group on this SME server, or is it not neccessary?

Kind regards

Librarian

Hi there,

I'm sure that if you fill in the "Delegate mail server" field, you are dropping the mail server role of the SME server and using another server to send and recieve mail. This will only allow you to use the other functions of the SME server.

From what you are saying, I think that you would have to specify a forwarding address for each user so that the mail first hits the SME server for spam and virus scans and then is forwarded to another server for retrieval. Not quite sure how the forwarding works but I assume that all mail that hits the SME server is scanned before being forwarded on but I could be wrong.

Hope this helps,

Arthur

Take a look here http://mirror.contribs.org/smeserver/contribs/bobk/SME_Manual/chpt-13.7.html

In particular the quote below:


"If you want to forward e-mail to another mail server for processing, enter the mail server IP address in the box marked Delegate mail server . A common use for this is if your server is receiving inbound e-mail from the Internet, but you would like to pass that mail to a different mail server on your internal network."

Thanks for the information, especially the tech-geeks postings. I've just wanted to make sure that this is what I wanted to do.

Now to activate the changes and see what happens...
