I had a company I was doing business with reject a valid email address of mine because it contained a “.” character in it. I got an error message about this being invalid email address to use. My “first.last@emailprovider.com” address had no problems sending/receiving emails with anyone else.
There should be some simplified standard way to identify what combination of email configuration is/isn’t supported by companies and email providers. This can also future proof against future changes in email configuration changing over time due to the ongoing fight against spam.
