Allow to create topic in categories via email

this site uses Discourse right? just now I enabled mailing list mode, that works for replying to posts and mentions via email, but seems it is also possible to create topics by email:

Usually I can’t access this site, OTOH I have email access most the time, also for an app like Delta Chat, and since the mailing list is kind of dead, would be nice if this forum can act as mailing list and forum at the same time with people seen posts and interacting which each part of the two worlds :slight_smile:
