Are we having email server problems?

[#1]

Suddenly getting "535 Error Authenticating" and "435 Unable to authenticate at present". Anyone else seeing this?
Edit: Now it's returning "451 Temporary local problem - please try later".

Yep - We've been getting a number of calls on this currently.
We've just put a message on the phone line.  I'll see if Bob's aware.

A problem has also been raised to Networks.

Hi guys,
We've took the servers which were causing the problem out of action whilst we fix it.
Should be OK now?
