Which ones? In RFC 5322 every address contains an addr-spec at some point, which in turn must include an @. RFC 6854 does not seem to change this. Or did I misread something?
Remember, we’re taking about regular expressions here so .+ means “a sequence of one or more arbitrary characters”. It does not imply that an actual dot is present.

If you’re posting long videos try to add in some form of tldr for those who don’t want to watch videos
That rejects valid emails

EDIT: I’M DUMB I THOUGHT YOU MEANT A LITERAL “.” , that regex is indeed correct.
Original:
This is a valid address:
user.name@[IPv6:2001:db8:1ff::a0b:dbd0]Relevant spec: https://www.rfc-editor.org/rfc/rfc5321#section-4.1.3
And you all doubted me… :P
Edit: Wait, I also don’t think local-part even needs a “.” in it? user@domain.com should be valid as well.
And it’s matched by
.+@.+as it contains an @.Remember, we’re taking about regular expressions here so
