There seems to be a problem with Yahoo blocking email from the mail gateway used by the forum. This means you won’t be getting any notifications or post digests.
I use the same company (Rackspace) for the forum and my personal email. Both are getting blocked so it’s not a problem with the forum itself.
The mail gateway for sending email is working okay. Messages are being delivered to other email hosting providers (e.g. Protonmail) and I haven’t seen any other domains bouncing emails.
As far as I can tell the gateway isn’t on a spam blacklist so I’m not sure what Yahoo’s problem is. I’ll pick up with Rackspace support and see if they can shed any light on it.
