Sorry to hear that you were having some issues accessing your email. Unfortunately I do see that there was a problem with the IMAP mail service on that server accepting new connections due to the IMAP authentication daemon having issues.
It looks like the issues did persist for roughly a half-hour, and I apologize for the delay in repair. It seems that POP email connections were still working during this time, which might have caused a delay in our system administration team fully noticing the resolving the problem.
Please let us know if you continue to experience any further issues at all.
Kind thanks for the response Jacob, email has been working fine since.
