This from the Email Battles Mailbag:

I’ve just used your diagnostic tool on yahoo.co.uk, only to discover (I’m gonna have a heart attack and die from this surprise) that BOTH servers for email at yahoo.co.uk are closed to inbound traffic. Do you know of anything that’s going on?

It was a huge problem most of the day yesterday, had a reprieve in the evening, and it’s a problem again this morning. How can they have only TWO servers for the UK - almost everyone I know here has a yahoo address.

D’oh! Great tool, though! LOVE IT! – Irim of Oxford

Hi Irim.
Good to see that the Mail Server Profiler could help. We use it to help network managers figure out their own mail server/DNS problems.

After checking my usual sources, I don’t know of any new Yahoo Mail troubles. Sorry. Keep us posted.
