I have an odd problem. One use started forums with a bad email addres (address@email.com, probably should have been gmail.com). Then the user decided to use their work email.
My server keeps returning a message saying "There was an error while attempting do deliver your message with [Subject: "MB0-S13: Re: Personal experiences about forecasting, or product/servicedesign - 1pt"] to rrg@email.com."
How do I fix this problem? The user's current email address is correct, but Moodle somehow thinks that this "email.com" address is still a forum user. In which Moodle database table might I find this bad email? Maybe a course table, or a forum table? Or other places? My Moodle is acting like it thinks this users should still get all forum posts, and it does not matter if a new forum is started, Moodle is still trying to email to this bogus user.
