One of the main problems with trying to validate an e-mail address with a regular expression is that the [url=http://www.ietf.org/rfc/rfc0822.txt]RFC[/url] for e-mail addresses allows almost any string you can think of as a valid address and if you use an expression that looks for the pattern /[a-z]+@[a-z]+\.(com\|net\|org)/, you will end up telling a lot of people with valid e-mail addresses that their address is invalid. As a quick example, I use a program called MailWasher to screen my e-mail before I get it from the server. MailWasher doesn't recognize that '+' is a valid character in an address and I'm getting more and more e-mails from mailing lists where people have decided to use '+' in their address. As a consequence, I get about five e-mails a day that MailWasher marks as being suspicious because it contains an invalid address. Take a look at the following links for a better description than I've given of how to validate e-mail addresses: [url=http://www.oreillynet.com/cs/user/view/cs_msg/11855]Regexp for validating an email address[/url] [url=http://www.oreillynet.com/cs/user/view/wlg/2379]How to Validate an E-mail Address[/url] [url=http://www.breakingpar.com/bkp/home.nsf/Doc?OpenNavigator&87256B280015193F87256C40004CC8C6]Valid Internet Email Address[/url].
