Michael Bailly commented on JAMES-3106:
---------------------------------------
My 2 cent: there is a difference between the action of enabling/disabling a
feature, and the technical parts that are needed to have the feature working.
Currently, defining a listener (technical endpoint) enables the feature, and
there is no way to disable it.
One solution could be to set a configuration option "IMAP operations go through
Spamassassin" that is either tr or false.

> Key: JAMES-3106
> URL: https://issues.apache.org/jira/browse/JAMES-3106
> Project: James Server
> Issue Type: New Feature
> Components: mailbox, rabbitmq
> Reporter: Benoit Tellier
> Priority: Major
>
> *Problem:*
> {code:java}
> Given a running James cluster configured with additional listenerA
> When I do a rolling configuration change to remove listenerA
> Then James keeps posting events in the queue corresponding to listenerA
> without consuming it
> {code}
> To summarize we can not remove additional listeners properly even with a
> restart.
> Impact: the queue keeps growing indefinitly eventually causing a rabbitMQ
> failure.
> *Temporary workaround:*
> Upon such reconfiguration an admin needs to manually delete the corresponding
> binding using rabbitmq admin interface.
> *Long term solution:*
> We need to provide an easier way to clean this up.
> - Deleting all mailboxEvent bindings upon stop is not an option as:
> - other james servers depends on it
> - james might not be stopped in a gracefull way
> - James could be sanitizing existing bindings upon start (removing the extra
> ones) but I'm worry about uneven configuration clusters. (serverA have the
> additional listener, not serverB)
> We could as well provide a cleanup endpoint for the admin to call once the
> rolling adoption is done. Something like:
> {code:java}
> curl -XPOST htt://ip:port/eventBus/workQueues?removeUnused
> {code}
> But I don't like relying on admins to remember to call it...
> Thoughts on this?
