Hi,

is there anything missing from my side, or something that I can do to help
that my patch can be included?

Regards

Bron,
We're starting to run into this same issue -- lmtp proxies fail to deliver mail when mupdate master craps -- and so started to investigate this thread. However, it doesn't look like Michael Menge's patch made it in. Your thoughts?

I'm convinced :) I'll probably add it with Ken while we're at CMU in a couple of weeks when we can test it together. This is precisely the kind of thing we love to see! Thanks.

Hi,

as we have had an other crash of mupdate master last week, we used the
patch on our production system.

After the patch was added the load on mupdate master was dropping form
about 10 to about 1.

After one week of using it we have not found any problems.
As I have not received any other feedback, I added it to the
bugtracker.

https://bugzilla.cyrusimap.org/show_bug.cgi?id=3866

Pleas consider adding it to 2.5 and 2.4.next

Regards

By thew way, the reason I was so surprised in the first place was, that
I have been fooled by the documentation:
Quoting https://cyrusimap.org/docs/cyrus-imapd/2.4.17/install-murder.php

Configuring the frontends
[...]
However, because the frontends only talk to the mupdate master
via   a  slave running on the local machine, you will also need
to set  up  a  slave on the same machine, in the SERVICES section
of   cyrus.conf,  like so
And an other misleading DOC !

thanks for your mail. By any chance do you still have the patch?
In fact, I don't.  Dusting off my notes, I recall now that instead
of patching this (bogus) code, we instead decided to configure the
frontends as "unified", while leaving the backends "standard".  The
 only downside of this approach was that a naive admin could
potentially create a user's mailbox on a frontend.

Sorry I said that we ported that code forward: in fact we simply
got  the effect of consulting mailboxes.db without porting forward.

:wes
I have patched my lmtpd to use the local mailbox.db in all cases,
unified Murder, and standalone cyrus already did this.
I tested it with a few testmails on my test system,
but as i don't have a unified setup or a standalone test system
at the moment i didn't test these setups.

I would appreciate a review.


Regards,

   Michael Menge
