I’ve installed the discourse mail-receiver to allow replies by email on my self-hosted site. I get the following deprecation warning in the logs.
Deprecation notice: warning: the email parameter is deprecated. all POST requests to this route should be sent with a base64 strict encoded email_encoded parameter instead. email has been received and is queued for processing (removal in Discourse 3.3.0)
At /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/actionpack-7.2.2.1/lib/action_controller/metal/basic_implicit_render.rb:8:in `send_action`
I am running the latest Discourse 3.5.0.beta3-dev, so the deprecation version is wrong, but it still seems scary that it could break any moment.
Deprecation in the source code is here
And here is the line that needs to be changed in mail-receiver to use base64 encoding instead. Let me know if you would like a PR.
