Issue Description: Some government organisations have tested turning off the family domain ‘GCSX’ on 29th June 2018 and this resulted in some organisations being unable to send emails to some email addresses ending .gcsx.gov.uk since then.
Latest Update and Guidance:This is in preparation for the retirement of the .gcsx.gov.uk domain in March 2019(https://www.gov.uk/guidance/securing-government-email). If you experience similar issues whereby you are unable to send emails to a local government organisation, then please inform them that you are not able to send emails to their .gcsx.gov.uk email address and to determine the best alternative means of communication.
