depends entirely on how the "secondary" is setup. there's no reason you can't have an MX over your fast cheap link, then a lower-priority MX over another, less-desirable link - and have both addresses resolve the same host. automatic failover in case the first link is down. or a beefy mail server, and a smaller mail server willing to help out during peak times - but both can do local delivery (because you have NFS mail spool, etc). > the clients check with the primary only for their email.
