Do you guys know that your own mail servers (mailenable.com) are down?
Sending a email to sales@mailenable.com returns this:
MailEnable: Message delivery has been delayed.
Message is waiting at xyz.co.uk for delivery to mailenable.com.
The message will be retried for another 24 hours.
Reason: Mail server for mailenable.com could not be contacted at this time. MailEnable will keep trying to deliver this message and will notify you of any progress.
