Is managing your SMTP connectivity a trial and error process that feels like dabbling in the dark arts? Have you been accused of being an open relay or told your MX and PTR records don’t match? Do your users POP your IMAP when they try to connect from their cell phone? This session gives you the understanding of the world you’re connecting to. We’ll cover all those DNS topics from A to SPF, the difference between POP and IMAP, and how make your Domino server speak to the rest of the world properly. Why? Most sessions on mail topics focus only on the Domino side of the equation. Domino administrators don’t always understand the rest of the picture well. By focusing on the core internet protocols that make mail routing possible, we’ll give admins the knowledge they need to run better systems. This session has a narrow focus design to allow more depth and detail than usual.
