We are aware of an issue users are experiencing when sending from our Hosted Email environment. Affected users will receive the error "451 4.3.5 Sender address rejected: Server configuration error" when attempting to send via email clients (such as Microsoft Outlook), Webmail and mobile devices. There is no effective work around for sending email at this time. This issue will only affect outgoing email. Incoming email delivery is working as normal.
