Add validator to restrict sender ids like NHSNoReply
NCSC are trying to reduce the number of sender IDs in use to help people know they are coming from a legitimate place.
One of the sender ids with lots of variation is NHSNoReply
This PR stops new people registering new sender ids with nhs and no and reply in any order, apart from NHSNoReply
Suggested content changes:
Text message sender ID must be ‘NHSNoReply’ - this is to match other NHS services
Text message sender ID must match other NHS services - change it to ‘NHSNoReply’
Text message sender ID must be ‘NHSNoReply’ to match other NHS services
To match other NHS services the text message sender ID must be ‘NHSNoReply’
To match other NHS services the text message sender ID must be ‘NHSNoReply’, not ‘{invalid sender id}’
Right now, I think my preference is:
Text message sender ID must match other NHS services - change it to ‘NHSNoReply’
