here's an idea:
if you would have all emails stored in the reverse order:
moc.niamod@resu
then all you would need is simple 'ORDER BY email'.
Also, in this way, emails like user@subdomain.domain.com would be perfectly
ordered.
Is that a crazy thought?
If not yet then: why not to add an additional field to the table with the
reverse domain only? (after an @) ordering by it. INDEX would also be
simple.
now is crazy? Then, is there any such function in PostgreSQL? With C it
would be so easy and fast.
Cheers!
