I have that running with what one of our clients. (were using sendmail
he's using SlMail f/NT)... it's quite simple.. there is this a command
that a server can issue to another one called "ETRN yourname.com". It
basically tells the server to process the queue for "yourname.com".
To get this working you:
- assign them an IP, that will never be reachable, unless they dialin.
- make it the primary mail exchanger for that domain.
- make your secondary mail exchanger one of your boxes.
- get their MS-Exchange server to ETRN yours.
So basically what this accomplishes, is all mail will never get the
main server unless they are online, and when they are the tell your
server to dump it's queue.
