My domain is still down. Using randy. Strangely, another domain on the same mail host works.
And here I was about to post that my mail had been working nicely for over a week now, since I'd complained about DH's email flakeyness.
I just noticed that there's a little clock icon next to my email address in the mail > addresses part of the control panel. Its alt is "change pending". I've not changed anything lately. What is this?
