Your mailer is Postfix, good ...

This is almost certainly a Postfix problem.  The feature that
recognizes "additional data" in the mailbox name (ie, the
"+9cb3f11e..." confirmation code) is apparently turned off.

Or it's possible that your aliases are configured incorrectly so that
"bbmodels-confirm" is not recognized as a local address.
