I would like to determine whether an email address is valid.
Is there a regular expression or something I can use to do this?

Have a look at Regexp::Common::Email::Address from the Regexp::Common modules.

Recipe 6.19, "Matching a Valid Mail Address", in The Perl Cookbook gives a broader coverage of this topic and is well worth a read. In it, Tom Christiansen refers to his attempt at a regular expression (while admitting that it's less than perfect) which can be found in his script, ckaddr. It is based on a regular expression in Recipe 18.9 of Mastering Regular Expressions. All of this proves (to me at least) just how tricky matching an email address really is.
