<div>Murder plus replication is a giant ball of suck right
now. They don't know about each other, and they interact
badly :(<br>

<div>So is that a case for documenting "Here be dragons, enter
at your own risk" for the moment?<br>

<div>Does it mean that admins should look at other backup
mechanisms to handle failover and redundancy in a murder
environment, because Cyrus's replication doesn't play nicely
with murder?<br>

<div>Or we need to fix murder and replication to work together
nicely, but that's hard work[tm].<br>

Ahem, some of us run Murderous Replicas all day long and it works
well enough... Doesn't it? ;-)<br>
<br>
I can write this up, I just wasn't sure if it was still needed. I
put a big ol' Note: in the replication page saying:<br>
<blockquote>
<div class="admonition important">
<p class="first admonition-title">Important</p>
<p class="last">Within a Cyrus <a class="reference internal"
href="https://docs.cyrus.foundation/imap/developer/architecture.html#architecture-murder"><em>Murder</em></a>
environment,
replicas must <strong>not</strong> be configured to invoke
<a class="reference external"
href="http://docs.cyrus.foundation/imap/admin/commands/ctl_mboxlist.html">ctl_mboxlist(8)</a>
on startup (pushing the local mailbox
list to the <strong>Mupdate Master</strong>). This may only
be done on the
Master instance.</p>
</div>
</blockquote>
That's the only real gotcha I know of, but, having said that, I did
write up a brief set of instructions about this very topic not that
long ago (IIRC) for user mailing list. I figured I could start with
that.<br>
<br>
