How to unsubscribe ALL users from ALL threads ??

[محروم.كوم]

Hotmail keeps adding my server to their internal 'spam list' - and I'm not on any 'official' spam lists, and Hotmail says it's probably due to the amount of emails my server is sending them.

Does anyone know of a way I can unsubscribe everyone from all threads and/or forums, so that they don't receive email updates when a new thread is created?


I just noticed that users can get updates when new threads are posted, because I read this msg below which got bounced back to me:

Dear


You are subscribed to the forum , there have been 94 new thread(s) and 1 updated thread(s).
_____



Is there a setting (or query) I can use that will go through the entire member list and remove everyone from notifications like this? __DEFINE_LIKE_SHARE__
