I've enabled bounce handling on my forums, but I'd be interested to know what it actually does. I very rarely use the bulk e-mail options and I can see that this has an option to exclude members that have e-mail addresses that bounce.
However, what happens to all of the other e-mails sent from the site - primarily notification/subscription e-mails. Are these put on hold when an e-mail account is detected as invalid?
Thanks, this is the part I wanted to clarify. I read something that seemed to suggest that subscription e-mails etc... were still sent out. It's good to know that all e-mails are stopped from being sent if a user is marked as invalid.
