Domain has outgoing email disabled error message

Hi All

first let me say i have already read the other post based on the same issue and tried solution but no luck.

My story is we had a Domain transferred form one hosting company to another yesterday and then while i was changing the nameservers the old hosting company which the domain was still pointing too decided to be nice and suspend my account before I could transfer my old emails.

Once the nameservers changed over last night i was able to send and receive emails however on a different hosting site i have a another domain which has a forward set up to the an email account on the new hosting, when we send any messages to the email address on the other email domain we get a bounce back saying

"Subject: Mail delivery failed: returning message to sender

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

boss@domain.co.uk

(ultimately generated from boss@domainwhichwetransfered.co.uk)

Domain domainwhichwetrasfered.co.uk has outgoing email disabled."

I tried the suspend and then enabling it again but i see get the same issue.

any ideas please would be ace

Many Thanks
