Yes, but that's delivery from an MTA, which obeys MX records and has some
idea of a host being down. Try getting Eudora to do things that way and
you're SOL. IMAP and POP also suffer from the same problems.

The Big/IP gives us redundancy with a max 3 second failover. Take a look
at http://www.f5labs.com; it might clear up what I'm trying to do.

Of course, now that Exim 2.00 is out, the question no longer requires an
answer...
