Does the url attachment and additional contact email only support .com formats currently in RSSP?

Summary:

In RSSP, for the add URL attachment and the additional email contact box, do this boxes only support certain formats such as .com?

There are links which the format it doesn't seem to support, and in education we use a lot of different links and domains. For example .education for the url and 'domain'.group was used for the email, both were shown as not valid email/url.

Is there a list of all supported links and email domains we can use? Is there a way for us to configure it so other domains and links can be use in those boxes? If not are there plans for this to be added in the future.
