Outbound email from Outlook Express for all my domains on server10 is failing.

chrastina.com is just one of seven domains affected.

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

I also opened a trouble ticket for this problem. I posted here so other customers are aware of the problem and are now informed that Hostony has fixed the problem.

Thank you, Alexander.
