Overnight, I suddenly cannot send emails. I keep getting an error code AUP #OUT-1500 that says: "The email address you are sending as must match the email address you used to auth. " But I have changed nothing. Everything worked fine Thursday when I went to bed; got up Friday unable to send. I can receive all day. And I can send using my provider's website, but I'd rather use Thunderbird as usual. What the heck just happened? None of the Support suggestions work. Thanks for any wisdom you can impart!
