You can see the hooks (and the variables they expose) by running sup -l.
I think you want the after-poll hook.  Something like this might work
(I'm modifying my after-poll.rb slightly)

  require 'cgi'
  notify_addresses = %w(
    someguy@example.com
    otherguy@example.com
  )
  from_and_subj.each do |m|
    next if notify_addresses.select { |a| m[0].include? a }.empty?
    msg = CGI.escapeHTML(m.join "\n")
    system("notify-send", "-t", "10000", "New E-Mail", msg)
  end

(the HTML escaping is necessary for notify-send to work, otherwise you
just get a blank popup).
