Update: Mail is being sent/recieved now.
sean Apologies for the trouble, DNS infrastructure is under attack, we're working on it.
That makes sense.
The DNS cache on my system must have kicked when I ran a ping
because those succeed. Not sure why my mail app didn't fall back to that at the time. Maybe it is now and that's why I'm able to send.
I'm glad to see those various status updates. I started this thread because I didn't see any at the time.
Thanks!!
