My mail server logs show about 20 failures in all of the last week until yesterday 20:43 CET, then 350 failures between 20:43-00:21, then nothing after that. So fair enough, from the client side rather than the status page it looks like 3.5 hours rather than 2.5.
But still, given that resolution time, the suggested solution of changing the SMTP server is absolutely ludicrous.
