Guest tuned Posted April 7, 2008 Posted April 7, 2008 We're doing some testing w/ a W2k3 SE vm and would like to test the ability for mail to be sent directly from the server without using Exchange. The VM currently has an internal address on our network but I can give it an external one if that helps in the matter. IIS has been added as well as a Default SMTP server. Authentication has been configured to "anonymous access" and relay has been set to allow "all except the list below" with the list empty. This is a stand-alone server not part of a domain so under the domain name for the SMTP settings all that's listed is the server name. I've tried opening a telnet session to the mail server and sending mail but emails aren't transmitted, even when the recipient is the same as the sender. Am I missing a step or is something misconfigured?
Guest Anteaus Posted April 8, 2008 Posted April 8, 2008 RE: Issues Configuring SMTP for 1st Time Portwise, to send outgoing mail the SMTP server needs to be able to accept connections from LAN computers on its port 25. With the standard firewall it needs no specific outbound setting. Do not expose port 25 to the internet -at least not without without authentication ON- or you'll be a spam relay. If you want mail to be accepted by other SMTP servers these days, the public IP address needs to be a static one (specifically, must not be part of a known broadband or dialup dynamic-IP range) and the domain the mail is purported to be from should have a PTR record for this IP. The PTR need not point anywhere specific so long as it's valid.
