Thank you so much for your efforts with this!
Ah ha great catch. So for those of us in this boat what would be the best course of action to take to immediately get back up and running? Is it safe to roll back in any way until the next version of bbPress is released?
Another twist for those of us that use Mandrill — $do_not_reply is used for both the to address and the from address. In order to get around Mandrill requiring the from address being legit and on file I first had to change $do_not_reply to be my main Mandrill address, which in turn addressed every single email to my actual email address instead of one that is intended to go nowhere.
I made another edit and customized the From address in $headers and all is well, but it’d be great to have both be separate filters for cases like this where the from address needs to be legit.
It looks like the issue is compounded by
// Setup the From header
$headers[] = 'From: ' . get_bloginfo( 'name' ) . ' ' . $do_not_reply;
as well. Mandrill complains that the format isn’t an email address and fails validation. Not sure if this is a change in the latest bbPress update but I had to modify that as well.
Running a few tests, it looks like the new BCC setup continues to work as expected through Mandrill.
I just found myself in this situation as well, took me a while to figure out what happened but you’re right when it comes to wpMandrill. I’ve just made the change a few minutes ago by hard-coding an email address Mandrill knows about, but I’m not sure how it’s going to react to BCC’ing all the recipients. Have you had any luck in testing/verifying it still works?
