Help extracting email address from email header X-RCPT-TO:

[CJWilson3759]

I Need help with regular expression to pull the email address from email header. The email header contains lots of text. I need to get the email address following
X-RCPT-TO: <sender@address.com>

I've tried #ReFind("[X-RCPT-TO: <]*[>]",header)# and that didn't work because I don't understand how to write regular expressions.
