Hostroute Email Down?

[Lee_Owen]

Has anybody's elses reseller email gone down? I'm not sure if the email has an internal or external problem.

An unknown error has occurred. Subject 'test', Account: 'mail.*******.co.uk', Server: 'mail.*******.co.uk', Protocol: SMTP, Server Response: '421 Unexpected failure, please try later', Port: 25, Secure(SSL): No, Server Error: 421, Error Number: 0x800CCC67

Edit: Doing a search shows the problem should be their end, I know it says server error above but I've had similar wording before and the error was my side.

All sorted, their server was full.
