Verifying e-mail addresses with a regex is not possible. It is possible to make some guesses, but a regex is not the best solution as one has little to no control over the structure of the e-mail address.

Try Email::Find. It will extract the e-mails for you. Documentation can be found here.

For the record, the following are all structurally valid e-mail addresses (though they don't go anywhere).

Alfred Neuman <Neuman@BBN-TENEXA>
":sysmail"@ Some-Group. Some-Org
Muhammed.(I am the greatest) Ali @(the)Vegas.WBA

The above examples were published in CGI programming with Perl, Second Edition. If you'd like more information, check out RFC822.

Cheers,
