Did you just add the aliases (custom emails) and it still didn't work, or were they there a long time? I didn't see them in the actual config, but I saw them in the DB. If they were old, it's possible they were lost during the migration to the new email system a few months ago. If they're new... then maybe the web script isn't working right to set them. I triggered the "change email" action manually for your account, and it appears they're in place now. Please try again and see if it works.
