I am sending emails from the erl shell from directory where the gen_smtp beam files are available.

/var/lib/rabbitmq/mnesia/rabbit@vm-gbbhat-003-plugins-expand/gen_smtp-0.12.0/ebin

it looks like,

{ok,<0.82.0>}

Rabbitmq logs show the error like,

I am trying to use rabbitmq-email only for receiving emails and putting them into queues, from there depending on the email content I will be taking actions.

Please help.

How did you build and install the rabbitmq_email plugin?

[gbhat618]

I downloaded the .ez files from this repository itself, (https://github.com/gotthardp/rabbitmq-email/releases) gen_smtp-0.12.0.ez rabbitmq_email-0.2.0.ez copied the downloaded .ez files to

/usr/lib/rabbitmq/lib/rabbitmq_server-3.7.13/plugins

and executed

rabbitmq-plugins list 

to ensure that the rabbitmq_email plugin gets detected. and enabled the plugin with,

rabbitmq-plugins enable rabbitmq_email

and restarted the rabbitmq-server with

service rabbitmq-server restart

[lukebakken]

Thank you for the very detailed information. There is a chance those binaries aren't compatible with Erlang 21.X. I will investigate.

In the meantime, you could try compiling this library yourself. make dist will create the necessary .ez files.

[gbhat618]

Yes. It is working now.

How I built the plugins

I made sure all the checklist in here is met - https://www.rabbitmq.com/build-server.html#prerequisites (erlang, elixir, gnumake, libxslt, xmlto, zip and unzip)

Then copied the plugins from plugins directory( within the local copy of the repository) to the rabbitmq plugins directory

Enabled the plugins

Restarted the server

I am using all the latest version for rabbitmq-server, erlang, and elixir.

Thanks a lot.

Fixed in the 0.3.0 release.
