rabbitmq-server failed to start after enabling the rabbitmq_email plugin

[Rohan-Rajak]

Hello there,

I have installed the rabbitmq_email plugin v0.4.0 in RabbitMQ 3.8.9 with erlang version 21.3.8.7. But after enabling the plugin when I restarted the rabbitmq-server service, the service failed to start. I checked the logs and it is related to the plugin. We have tried with the plugin version 0.3.0 but the issue is the same.

I have also tried with RabbitMQ version 3.7.x but the result is the same.

To make sure that the issue is with the plugin, I disabled the plugin and tried to restart the service again. The service started without any issue.

It will be really beneficial if you may help with this issue.

Hello there,

Please find the following information as required-

• Operating System: CentOS Linux release 7.7.1908 (Core)

• I downloaded the .ez files of the rabbitmq_email plugin and gen_smtp plugin from https://github.com/gotthardp/rabbitmq-email/releases -> copied the .ez files into the plugin directory of rabbitmq -> then ran the command "rabbitmq-plugins enable rabbitmq_email" to enable the plugin

To disable the plugin I ran "rabbitmq-plugins disable rabbitmq_email"

• Log files are attached

Hello,

@Rohan-Rajak RabbitMQ 3.8.10 will ship with a fix for this. Please watch the rabbitmq-users mailing list for announcements about Release Candidates and test with an RC in your environment.
