Guest Jaz Posted August 20, 2007 Posted August 20, 2007 Can anybody give me information on what it would take to setup a SMTP mail relay server on our DMZ. Or Could anybody direct me to some documentation on setup and configuration on this server along with what needs to be done to the firewall. Thanks, Jasper
Guest Leif Pedersen [ MVP] Posted August 20, 2007 Posted August 20, 2007 Re: SMTP Mail relay server Hi, You can use for example the SMTP that is included in windows server IIS. For it to work you need to configure your SMTP domain as a non local domain and forward all mails for this domain to your internal exchange server. You need to allow your exchange server to relay through the SMTP server and you need to install antivirus and antiospam software on the server. The firewall needs to have SMTP port open, NNTP port, DNS port and the ports your antivirus and antispam needs for updates Leif "Jaz" <jrecto99@yahoo.com> skrev i meddelelsen news:OCkOkb04HHA.5740@TK2MSFTNGP04.phx.gbl... > Can anybody give me information on what it would take to setup a SMTP mail > relay server on our DMZ. > > Or Could anybody direct me to some documentation on setup and > configuration > on this server along with what needs to be done to the firewall. > > Thanks, > Jasper > >
Guest Enkidu Posted August 20, 2007 Posted August 20, 2007 Re: SMTP Mail relay server I would only open ingoing port 25 on the firewall for traffic to the exchange server from the mail Relay. I would allow outgoing port 25 to any Internet address, but only from the Exchange server. You should not need DNS ports to be open if the Relay has a DNS client and is configured with external DNS servers, and then only if the Mail Relay is checking DNS of incoming mail for AntiSpam. I would configure only the IP address of the firewall in the Relay's 'hosts' file. I would configure the SMTP Relay to get its own Antivirus and AntiSpam updates. I don't see the need for the NNTP ports unless you are doing News, which most people don't.

Guest Jaz Posted August 24, 2007 Posted August 24, 2007 Re: SMTP Mail relay server Is there a way to test this server without having to change the firewall routing. I want to make sure that once we change the firewall, we the server will work properly.

Guest Mr.B Posted September 2, 2007 Posted September 2, 2007 Re: SMTP Mail relay server Is there a way, to block or to pass relay test, when you encapsulate fake e-mail … "someone@email.com"@pass.email These is Test 8 on http://www.abuse.net/relay.html.
