The devil is in the details. If your home broadband ISP is going to host your DNS, you _must_ inform your domain registrar, Netsol in this case, of your new DNS servers' and their IP addresses. Then you must explicitly tell your broadband ISP exactly what records you want in your zone file and the contents of each record. To minimize downtime (lost email), you'll want your broadband ISP to already have your DNS zone created and ready _before_ Netwol switches your domain records. Your TTL is 900, or 15 minutes, so you shouldn't have to worry about any lost mail during the DNS switchover, ASSUMING YOU HAVE EVERYTHING ELSE SETUP CORRECTLY. >> You _must_ read up on the basics of internet mail server configuration >> before you continue this journey of yours.

The only relevant RFCs in this case are the SMTP RFCs, 2821 and 2822: http://tools.ietf.org/html/rfc2821 http://tools.ietf.org/html/rfc2822 If you're running an internet mail server (SMTP) at you home, POP/IMAP will be handled on your local private network, and thus aren't part of the current discussion. I guess this would be a good time to point out that you haven't yet mentioned how you plan to get to the mail that's delivered to your MX, or what you plan on having your MTA do with internet mail once it arrives. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
