There are other rules to being a valid email address IIRC. I remember doing some of this in the past, and it can get complicated. For example a single period is valid, but 2 periods in a row is not. Also period dash ".-" and dash period "-." isn't valid either. Back then for the host/domain portion the top level domain could only be 2 or 3 characters. I know it's more now (ie .info). Names (the part before the @) must end in a letter or number. Etc...
So you might want to divide on the "@" into a name portion and a host/domain portion and test them individually. I finally ended up writing code to get the MX for the domain, opening a connection to it, tell it the recipient's name and close the connection not sending any actual email. If everything passed, I was fairly safe that that the email was at least valid for someone. But I didn't do with is UV/UD, it was on a web server, could have been perl or more likely PHP. I probably have that code somewhere if it would help.
