An issue was reported wherein ScribeManager did not recognise an email address and therefore would not permit it to be entered for a contact.  This happened because the contact in question had just changed their dns host and the new host had not yet propagated.  This issue will self-rectify once the new dns details propagate, which normally takes 24-48 hours.  In future cases, please contact ScribeManager support and request that they add the email address manually.
