Well, I left that for the OP to figure out. Still, your regex is worse - a domain name cannot contain '%'. The only valid characters for a domain name are letters, numbers and a hyphen. Also, maximum length for a domain name is 64 characters, which could/should be checked too. > But, even that still doesn't cover all the possible and legal Unicode > code-points that can exist on both sides of the @ of an email address.. No, they can't. There are no 8-bit characters allowed in an email-address. Check out RFC2821. > tedd@ˆ.com > > is a legal and working email address. If that reads "tedd(at)<space>.com", it might be valid on your system, but not in public. /Per Jessen, Zürich
