未完了ActionMailer need to limit how many maximum connections it opens
0%
説明
Microsoft office 365 smtp server has made some changes that will cause
this error message
Email delivery error: 432 4.3.2 STOREDRV.ClientSubmit; sender thread limit exceeded
basically
New throttling limit for concurrent connections that submit messages
The service has various limits to prevent abuse and to ensure fair use. An additional limit is being added. Under the new limit, up to three concurrent connections are allowed to send email messages at the same time. If an application tries to send more than three messages at the same time by using multiple connections, each connection will receive the following error message:
432 4.3.2 STOREDRV.ClientSubmit; sender thread limit exceeded

other projects have worked around it by introducing a
maxConnections: 3 limitation to there mailers

Could you try again after adding the following lines to config/additional_environment.rb?
<pre>
config.active_job.queue_adapter =
ActiveJob::QueueAdapters::AsyncAdapter.new \
max_threads: 3
</pre>

The problem seems fixed so far. So there a way in the future to only make this affect the mailer. I guess this is now a global settings to any class that wants to use the ActiveJob::QueueAdapters::AsyncAdapter.
