Rails Actionmailer - Find original header in bounceback

I've set up a forwarder through cpanel called 'eblast-bounceback@mydomain.com' which pipes to a runner (i.e., look up any tutorial on receiving emails through rails). This part works just fine - I can tell that the script is running because I've set it to use the logger. The problem I'm having is being able to find my custom header "X-Subscriber-Id: " within the bounceback email. Is there a way to access the raw email data so I can just do a regex search or do I have to do this in a more complicated way?

On another note, is it wise to au开发者_开发知识库tomatically remove the email from the database if I get a bounceback or is there some sort of addition steps I need to take to avoid malicious intent?

EDIT: Posted Code...

def receive(email)
    # email.body doesn't work...how do I search for this?  I know it's in the email...
    account = /X\-Subscriber\-Id: (.*)/.match(email.body)[1].split("|") rescue nil
    # If we've found the account info
    logger.info "Nil?: #{account.nil?}"
    if !account.nil?
        id, private_id = account[0].to_i, account[1]
        if @subscriber = Subscriber.find_by_id(id)
            @subscriber.update_attribute(:bouncebacks, @subscriber.bouncebacks.to_i + 1)
            logger.info "Faulty Account: #{@subscriber.email}"
        end
    else
            # This is where we email the admin in case of failure to find an account (manual removal from database)
            # This section is incomplete at this time
        @from = "My Site <admin@mysite.com>"
        @recipients = "admin@mysite.com"
        @subject = "Bounceback could not be processed"
        #@body = email.body -- What do I put here to simply re-send the email?
    end
end

Used email.to_s instead of email.body.
