Just so I have this straight, would someone check me out on this procedure. What I want to do is move the destination for a bunch domain names from one machine - machine A - to another on a different network - machine B. After the move, I want any residual mail in the Internet mail system delivered to machine A due to cached DNS info to be redirected to machine B by machine A.
Currently machine A is the preferred MX server in DNS-space. Using webadmin, I have all the domains for which A accepts mail listed under "Locally-hosted Domains" on A, which causes them to be listed in /etc/courier/esmtpacceptmailfor.dir/webadmin, and hence, I assume in the database in /etc/courier/esmtpacceptmailfor.dat. Mailboxes for each domain are supported by a MySQL database which references a mailbox, or possibly a .courier file in an alias directory. My reading of the documentation indicates that to switch to another server I need to do only the following: 1. Set up machine B in DNS-land as the low number (preferred) MX for each such domain name for which I want mail relayed. 2. Make sure that mail to each mailbox or alias in said domain on machine B is deliverable locally, just as it had been previously on machine A. Do I need to disable delivery on machine A so that mail to those mailboxes for which it previously accepted delivery are no longer available, or will Courier simply look at the MX records, note (on box A) that it's no longer the preferred MX, and automatically requeue it for delivery to machine B? -- Lindsay Haisley | "Everything works | Accredited FMP Computer Services | if you let it" | by the 512-259-1190 | (The Roadie) | Austin Better http://www.fmp.com | | Business Bureau ------------------------------------------------------------------------------ Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.
