    bbPress sends forum and topic notifications as bcc headers on one email. Postmark only allows 50 bcc on an email, so bbPress notifications can start failing on popular threads.

    Here’s a filter on wp_mail that will chunk your bcc headers into multiple wp_mail() calls, thus overcoming the limit!
