A solution has come to me but I was unsure if this would work. Rather than use these pop before smtp or other hack to get authorization can anyone tell me if this idea is feasible? The mail server is going to become a DNS server. And some clients will be using a dyndns type of entry to route a domain we collect email for. I know that sendmail will allow relay for users who have a reverse DNS that resolves to any domain name it is setup to accept email for. This will soon be doing its queries on a local name server which will have domain names set dynamically for some users. If the client uses a dyndns app to update the ip in bind before checking email then when sendmail checks to see if the user hostname is should resolve the one routed by our system and not the one assigned by the Dialup ISP or Hotel LAN service provides. Am I on the right track with this thought? Because if this is even remotely possible I would rather go that route since it is something we will be doing in the next several weeks. ----- Original Message ----- From: "jason" <jasonc@concentric.net> To: <freebsd-questions@FreeBSD.ORG> Sent: Wednesday, July 18, 2001 11:38 AM Subject: Sendmail and SASL > I am trying to build a mail server that can be used to send and receive > email from anywhere on the internet.
