Routers tend to allow all traffic out, but I can't find any reason to port forward DNS queries into a LAN. I never connect servers directly to the internet - I think that's crazy. I always hide them behind routers running NAT. So the question really is, is there a reason to allow the outside world to query my private DNS service? -----Original Message----- From: Jake Vickers [mailto:[EMAIL PROTECTED] Sent: Thursday, December 29, 2005 8:57 AM To: [email protected] Subject: Re: [qmailtoaster] open dns ports...

When you type an email (such as the one I use for the mailing list, [EMAIL PROTECTED]), your server needs to be able to query DNS to find out who millenia-llc.com is, and what their MX record is to actually deliver the message to. ------------------------------------------------------------------ --- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- No virus found in this incoming message.
