No, when the primary goes down, you just set queuelifetime on the
secondary according to how long it will take the primary to come back
up. Or you discard the primary and just start using the secondary
immediately.
In general, using a secondary gives you more control over what happens
when the primary goes down.
Also, using a secondary means that when the primary comes back up, a
quick `qmail-tcpok; svc -a /service/qmail' will bring all the mail
over to the primary immediately; you don't have to wait for varying
timeouts across the Internet.
