Hello, thanks for this information. It may no longer be accurate.
I use an installation with version 3.2.2, and wish to set a custom email address for my category.
Under “Setting up incoming emails for a category”, there is no “Accept incoming emails sent to:” tick box in the settings.
Also I don’t understand how the custom incoming email address works. Discourse does not control the email server, right? Do I need to do anything with the email server?
