Ruby email check (RFC 2822)

Question

Does anyone know what the regular expression in Ruby is to verify an email address is in proper RFC 2822 email format?

What I want to do is:

string.match(RFC_2822_REGEX)

where "RFC_2822_REGEX" is the regular expression to verify if my string is in valid RFC 2882 form.

Based on the answers to this similar question, you may want to reconsider using regex for this.

Does regex validation based on RFC2822 rules (it's a monster of a regex, too), it can also check that the domain is valid in DNS (has MX or A records), and do a test delivery to validate that the MX for the domain will accept a message for the address given. These last two checks are optional.
