Documentation Bug:

"Add a line similar to the following in the STARTUP section of
cyrus.conf"

There is no "STARTUP" section, it is the "START" section.

START {
  # do not delete this entry!
  recover       cmd="ctl_cyrusdb -r"
  # this is only necessary if using idled for IMAP IDLE
  idled         cmd="idled"
  # Start the replication client (this is the master)
  syncclient       cmd="sync_client -r"
}


If this method is used the master will wait till the syncclient can
reach the replica. This can cause unnessesary delays it the replica
is not running or can't be reached.



Reading the quote -
"Rolling" replication means that the "master" server continuously
synchonizes itself with the replica.
- I take this to mean that the master continuously *pushes* changes to
the replica [secondary]?

Yep.

Is there a recommended/suggested value for sync_repeat_interval other
than the default of "1"?

?

Is there a recommended Method for bringing up a new replica for an
active master (with 1.4 million messages in its mailstore)


If the replica is running, you have to run the following command
to initialise the replica:

sync_client -u -f userlist.txt

userlist.txt is a file containing all users.
This can be done while the master and rolling replication
is running.
