Users aren’t receiving notification emails

Hey guys

Recently discovered that users aren’t getting the bbpress emails when someone uses the @mentions or uses the “reply” button on thier individual posts.

My undersatnding is if one poster desires to repond to someone’s post or wishes to enage with them if they use either one of the two aforesaid feature then the said someone will be notified. Well, they aren’t getting the emails.

Any suggestions on how to fix this? Perhaps there is a feature in the plugin i can use? Thanks
