Until the mail gets delivered to the primary, the users see nothing.

After some while, yes. It may take some period for the secondary
to realize that the primary is up and running. You may speed it up
by running qmail-tcpok and ALRMing qmail-send on the secondary.

Exactly.
If you think about secondary to be a full mail server (with mailboxes
and all that) which takes over also POP3 and IMAP during
outages, it's not trivial to do (and usually not worth the effort; a
redundant cluster or inteligent switch is better then).
