Issue Security blocking customer notifications?

(EDIT)  I believe I found the solution, I had not added Customer Portal access to the security issues.

(Original)

Morning, I have discovered that some of our customers are not receiving customer notifications.  After checking all the notification settings I was unable to find any reason they would have stopped for certain users.

All issues do have a request type!

The only change I made that I think may effect it would be that we added a new default security level to all incoming issues.  However, even after that was added some users are getting notification while others are not.  Can security level block customer notifications?

Ideas?

I believe not having Customer Portal access to the issue security types was preventing notifications.

So if a user is reporter of an issue from which the same user is blocked because of issue security, this same portal user won't receive notifications from the issue ?

Even if someone comments "reply to customer" on the issue ?
