My regexp: [^@]+@[^@]+

  That fails on the perfectly valid email address: "Foo@bar"@example.com Although if that's your email address, you deserve everything you get ;) If you want to verify if an email address is valid, just ask your mail server if it is capable of sending mail to it: root@flan:~# /usr/sbin/sendmail -bv '"Foo@bar"@example.com' "Foo@bar"@example.com verified root@flan:~#

    Does it fail? I don't see ^ or $.

      I assumed it was anchored and he missed those off.

      The regexp looks for exactly one '@'-character preceded and followed by at least one character that's not an '@'-character. Or, in other words, it does not allow for an email address with more than one '@'-character.

        The point of the post was that since the regexp doesn't include start or end of a string it would still succeed: "Foo@bar"@example.com -> "Foo@bar"

    I don't need those “perfectly valid” email addresses. Person who create such addresses potentially dangerous.
