Re: frightening message

Cyrus provides a replication feature 
<https://www.cyrusimap.org/imap/reference/admin/sop/replication.html> 
*which is not called Murder*. Cyrus Murder 
<https://www.cyrusimap.org/imap/reference/admin/murder/murder.html#cyrus-murder> 
is a distributed server scheme, in which one deploys front- and 
back-ends.  Users access the front-end servers, which consult a 
"mupdate" database to locate the corresponding back-end for any given 
mailbox.  More here: 
https://www.cyrusimap.org/imap/reference/admin/murder/murder.html

Cyrus replication, on the other hand, allows one to maintain a "master" 
instance which uses IMAP protocol to replicate mailboxes, sieve scripts, 
etc. to one or more replicas.  You can read all about it here:
