This is still a huge problem, all emails are not working from bbpress.
so what do you mean by ‘activation’ ?
bbpress just uses wordpress ‘registration’
bbpress has ‘subscriptions’
so not sure what ‘activation’ you are meaning?
bbpress doesnt send any emails… activation emails, forgot password, subscription, etc..
the page bbp-register shortcode has register option which sends an email but since no email is sent no user can register.
ok start with
https://wordpress.org/plugins/check-email/ and set up logging
this will tell you if the site is trying to send emails, and you can see what address it is trying to send from, which I suspect is what your email system does not like.
if it is the sending email address, you can change this using
bbp style pack
once activated go to
dashboard>settings>bbp style pack>Subscription Emails
ok its working, its the buddypress emails that dont work. thank u
