I’ve noticed a difference in behaviour between the email domains whitelist setting at registration - and the automatic registration email domains setting in manage groups.
I work in the NHS where users have email addresses with sub domains emails @organisation.nhs.uk
The whitelist lets them all register by adding top domain [nhs.uk](http://nhs.uk) to the list. That works well for me.
If I add the same top domain [nhs.uk](http://nhs.uk) to automatically add them to a group - it doesn’t add them - at least not retrospectively.
I would like the automatic group registration to behave as the whitelist does. I’ve tried a wildcard character asterisk but that doesn’t work.
Do you have any suggestions - other than going through and adding every sub domain?

Why would retrospective addition be expected here? Couldn’t that be surprising and possibly even dangerous in other contexts?
(Thinking about this more, perhaps a dynamic pop-up prompt “do you want to make this retrospective, it will affect {x} users?” would work better?)

Yeah there is an inconsistency internally, our automatic group membership is based off a strict domain match per:

Our matcher for the `email_domains_whitelist` uses this match

I think it makes sense to make this coherent and consistent.
@techAPJ can you adjust the group regex.. carefully and make sure it is tested so it also allows subdomains.

Discourse 2.4 does give this prompt to include member already registered with the domain. It’s a great feature and works well, aside from this inconsistency.
