I am increasing getting message sending failures from mailer-daemon@secureserver.net saying that the message has been in the queue too long.

Grateful for a fix or advice.

Did you try to send one email to a number of recipients? If yes, how many recipients ?

If many recipients, were they listed individually or did you use a 'Mailing List' name in the TO field?

What sort of content did the email contain eg: simple hello correpondence or did it contain business contact type info with html and images etc or attachments (if yes what sort of size) ?
