You can put two MX like this : machine-a IN MX 10 machine-a.network.us. IN MX 20 machine-b.network.us. if machine-a is up, then the mail will arrive there. If not, the secondary MX machine-b will then receive the mail and queue it for machine-a. When machine-a is up, you can run the queue (sendmail -q) on machine-b. Some providers use a mailertable to put the mail to machine-a in a separate queue (using a special mailer entry) and then run the queue whenever the machine-a calls. It is a little harder to set up but works too. -- Ollivier ROBERT -=- The daemon is FREE! -=- roberto@FreeBSD.ORG FreeBSD 2.2-CURRENT #5: Fri Jul 14 12:28:04 MET DST 1995
