If you use LDAP routing (or any other form of recipient verification)
you can reject bogus messages during the SMTP conversation.  Puts less
work on your server and your postmaster, because he doesn't have to deal
with the double-bounces caused by viruses and spammers sending mail to a
non-existent address from a non-existent address.
