Reply To: Email notifications not working; looking for help
In some cases, it might be because the subscription emails are now being sent with all subscribers bbc’ed in rather than individually from a created no-reply address. The reason for the change is that posting new replies or topics was taking too long as it cycled through sending those emails. However, for some people (myself included), that wasn’t an issue.
You can go back to the previous way as outlined here (as I mentioned, I have similar code in a plugin) but it should work if you put it in a file called bbp-functions.php in your bbpress theme.
Actually, you might — after doing all the things you would do before you install a new plugin — try going back to the previous way with this: MJJ bbP 2.5.3 Subs. It does what it says on the tin, just uses the old functions from bbPress 2.5.3 to send subscription mails. Again, it might slow down new replies or topics. It doesn’t for me but just keep an eye on it.
