A while ago on this list I posted a few questions about an eregi filter for email addresses entered into a form. With the help of people on this list, I settled on the following code which has worked fine in the months since I started using it. The code is this:
eregi('[EMAIL PROTECTED]', $email)
But recently, a person was unable to get their email to pass this eregi test. The email is valid, as they are able to send email to me. It has the following format:
[EMAIL PROTECTED]
Shouldn't this email pass? I've allowed for hyphens after the @ mark. Is it that there are two many periods?
No, your expression is really excluding many valid addresses. The RFC specify a much larger number of valid characters. You are also only allowing one possible dot in the domain name.
I think it is better to allow some possibly invalid sequences and then perform a DNS/SMTP based validation. In that case you may want to try this e-mail validation class that performs first a regular expression based validation with a more complete expression and then performs DNS/SMTP based validation.
