As far as I can tell, the emails did not go out, as I've asked a few people if they have received it. Also, if this is how it's suppose to work, why did the email listing all recipients show up in the error logs with the error message?
I very rarely use the bulk email feature, possibly only once a year, if that. I would really like it to work when I do need to use it, like in this case when I need to let people know of the new link to the forum.
Thanks Marc.
