If your needs are checking email addresses=E2=80=99
validity, you really want to use something like=C2=B9

/^([a-zA-Z0-9&_?\/`!|#*$^%=3D~{}+'-]+|"([\x00-\x0C\x0E-\x21\x23-\x5B\x5D
-\x7F]|\\[\x00-\x7F])*")(\.([a-zA-Z0-9&_?\/`!|#*$^%=3D~{}+'-]+|"([\x00-\
x0C\x0E-\x21\x23-\x5B\x5D-\x7F]|\\[\x00-\x7F])*"))*@([a-zA-Z0-9&_?\/`!
|#*$^%=3D~{}+'-]+|\[([\x00-\x0C\x0E-\x5A\x5E-\x7F]|\\[\x00-\x7F])*\])(\.
([a-zA-Z0-9&_?\/`!|#*$^%=3D~{}+'-]+|\[([\x00-\x0C\x0E-\x5A\x5E-\x7F]|\\[
\x00-\x7F])*\]))*$/

=E2=80=A6as
" spaces! @s! \"escaped quotes!\" "@yahoo.com
is a perfectly valid email address.

(Note that
" spaces! @s! \"escaped quotes!\" "@=C5=82=C3=B3d=C5=BA.pl
is also a perfectly valid email address which the above doesn=E2=80=99t mat=

You might want to check
