Cyrus performs pretty well already. Background redundancy would be
awesome. Especially if we had control over when the syncing process

mysql does not have multi-master functionality, and it's replication,
is quite honestly, a joke. You may have mis-spoken and are talking
about the up-and-coming mysql cluster or the mysql max product (both
of which i'm much less familiar with).
Indeed i was talking about mysql cluster (which

we want is lazy replication, where the client gets instant results
from the machine its connected to, and the replication is done in the

Hello,
as Ken Murchison told me you could help me on my authentication problems, I
send you the scenario.
My main problem is to make Frontend services like LMTP and POP authenticate
against backend. Users are capable to authenticate either as SASLDB or as
LDAP users.

I believe that is called rolling replication.

Hello,
All that you say is true. But for performance one either
buys bigger and better or multiple machines to spread the
load. Murder allows one to buy multiple machines.
All I am saying is that improving perforance may already
be done. I believe redundancy in the application is more
important at

Hi all:
Does cyrus-imapd server have the limit of long size of mailbox name?
For example:

Is there any limit with the login name? If yes, what's it?
I believe this is MAX_MAILBOX_NAME which is set to

My vote would be for active/active, its usually more reliable and of
course it builds in better scaleability. I imagine the the main
question of everyone will be how the choice of active/active or
active/passive will effect cost/time of implementation.

My biggest question here is, simply, why recreate what's already
out there?
There are a number of projects (LVM, PVFS) which do this kind of
replication/distribution/virtulization for filesystems.
There are a number of databases which have active/active clustering
(mysql, DB2, Oracle, et al) and

FreeBSD 4.X printf() and friends support the %llu format. scanf()

One way to fix it is attached. My autoconf foo is lacking so I
