Why is everyone else suggesting new functions?  This works (in 6.5.3):

   ORDER BY lower(substring(email from position('@' in email)+1 )),
lower(email)

remove the lower() functions if you don't need them (I had mixed case
addresses).

I am guessing/assuming that it's cheaper to just use entire email address
in second key rather than extract before the '@' character.
