I’d like to start investigating new post by email and am trying to configure things to check an email inbox we maintain elsewhere. I’ve got incoming (email_in) and the associated config lited in Start a New Topic via Email ✉ configured and am looking at the category configuration on the category I want these emails to arrive in. I can set the “Custom incoming email address” setting, but I don’t see where I would configure pop3 polling for that mailbox - everything I can find about setting up polling has to do only with self-hosted account and not discourse.org accounts.
Does this mean that custom pop3 accounts aren’t available for discourse.org sites and that I just need to forward email to the discourse-generated incoming email address? Or am I totally missing some step in the documentation somewhere?
