This doesn't happen very much but when someone subscribes to a forum or thread on the site and they're email address is invalid, the administration inbox constantly gets bombarded with undeliverable email notices.  Therefore from now on any undeliverable emails that we receive, we will unsubscribe that user from any forum subscriptions.

So in short if you want to subscribe to threads make sure you email address is up to date on the the system.

See this post on changing your details including email address:
