Hi there,
I need help pls..I'm using c# on a webform and I have this regex validation
for email addresses: ValidationExpression
="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)* "
I'm having isssues when submit an email with single quotes --example
jane.O'(e-mail address removed) -- I would like to be able "to allow" single quote on
the email address. Can anyone help me out !!
Thanks ahead,

Angel

That single quote is not valid in an email address.

As I've always adhered to, yet annoyingly it seems some ISPs don't behave
themselves and have handed or allowed emails with a single apostrophe.

I've come across it once in the past where I've had complaints from people
with illegal apostrophes in their addresses and them not being able to get
through my validation.
