Is it possible for one master to rolling replicate to more than one

can't determine how to do this within the imapd.conf file. I swear I
read that you can have more than one replica. Can you let me know if
I'm mistaken?

Thanks for any help.

You cannot replicate from one master to more than one replica.
However, you should be able to replicate from master to replica, then
from replica to another replica.
Ie. Master->Replica1->Replica2
I realise this will introduce a small delay in the replication from
Master to Replica2, and will rely on replica1 being available, but it
should still be a valid option.
Cheers,
Roland
