> rejected name@clientname.healthcare emails For years I've had a catch-all subdomain to give out addresses like company@sub.domain.tld which makes filtering out the junk when companies invariably sell their email lists or get hacked much easier. It is getting rarer, but I still occasionally run into sign-on forms that don't allow more than one “.” after the @ unless it is due to a recognised two-part country suffix like .co.uk. I would never use something that isn't a country TLD for email for this reason, I assume there are a lot of bad systems out there that will incorrectly see them as incorrect.
