recover or re-instate old email comcast email

I am currently an email only user from back in the comcast.net days.  I just discovered that I was using an old comcast email address as a recovery address.  The old address no longer exists as it hasn't been accessed in years.  Is it possible to re-instate the email account long enough for me to receive a recover email there?  I tried to add it as a new user, but my account says I can't do that as an email only customer.
