Hello,
we are experimenting a bug in the subscribtion management. Kunena behavior does not fit with the 2 parameters of the configuration menu (users / subscribtion). We have tested it in 2 different web sites, with 2 versions of Kunena : 5.1.19 and 5.2.
When we expect that one subscriber to a category, should receive a mail when a new topic, but should receive another mail only when the first reply to this topic, but should not receive more mails when the next replies. But, today, Kunena sends emails to all the subscribers of a category, for each reply, eventhough the user did not subscribe to this topic.
Thanks to provide us with a fix for this issue, which discourages our users to use the Kunena forum.
Best regards,

It seems, the problem are the category subscriptions. Instead of mails only on new topics, it sends mails on each New Post. I've already added this error in our bug list.
Try to disable the mail delivery for one of these options (category or topic subscriptions).

Hello, 
this bug has a major impact on our website : I was expecting around 100 or 200 emails sent every day, but instead, we have several thousands of mails, as Kunena generatet a mail notification on each answer to a topic. Then, the mail system of our site host server is full with thousands of mails in its mail buffer, which blocks the mailing system.
So, could you make sure this bug is still open, and could you get a resolution date ?
Many thanks, ...

someone has checked if it is still an issue on kunena 5.2.2 ?
