Also in the FAQ article is a reference to the email archive manager ... which lets you see whether Zen Cart sent the emails out or not ... and (apart from CC middle-digits and password-resets ... neither of which ever get archived, for security reasons), if the email exists in the archive, then the mailserver didn't reject it ... and thus any failure to deliver is a result of problems existing "after" the mailserver grabs it. This could include blacklisting of your server's address, etc.
