We're a county government entity and our domain address is @co.geauga.oh.us.

When I make changes while in the users details tab and click save, the system reports that the e-mail address is invalid.

It does appear to save the changes though.

Thank you for your time and attention..

Can you give me an example? i tried with yaf@co.geauga.oh.us and the regex works as expected

I tried changing the e-mail address to me@home.com, and this saved. Changed back to the original and it errored out stating it was invalid and it e-mail address is still me@home.com (which I can change in the db, no problem).

Thank you again..
