Spaces are accepted before @ sign about deep-email-validator HOT 4 OPEN

I also have another corner case which I would expect be caught: [email protected]. is actually reported as correct if the typo check is disabled.
I would expect this to be caught by the regexp validation. It is very annoying as many modern browsers add a period when pressing space twice. I can easily trim the input but that won't remove the trailing dot.

Checking for spaces is beyond this

The philosophy of this lib is to be really light on validating the format of an email as that notoriously produces a lot of false alarms. Spaces are actually valid I believe in some cases, so I won't be adding that. If you want just regex I recommend validator.

The latter complaint is fair though. This lib should definitely validate that the email should not end with ..

Should add

   if (domain.endsWith('.')) {
      return 'Must not end with "."'
    }

I agree that you don't want to generate too many false alarms. Though I'd expect that spaces are only before or right after characters such as <> or "" that mark a readable name associated with the actual email.
There certainly should not be any spaces in the actual email part, though I must admit I'm not sure to put that together in a reliable RegExp ;).

Isn't is a valid domain? So email should also be valid in this case.
