  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?

    This is a valid address: user.name@[IPv6:2001:db8:1ff::a0b:dbd0]

    Relevant spec: www.rfc-editor.org/rfc/rfc5321#section-4.1.3

    And you all doubted me… :P

      And it’s matched by .+@.+ as it contains an @.

      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.
