Ok...  I know, and am finally using, a backup MX scheme so if the
primary mailserver has an issue at least the mail will have a place to
go to until the primary is back on line.   Is that what you're talking
about or do you have some magic where it's possible to have mail
delivered and picked up from both a primary host and a secondary
that's ready to take over if there are problems with the primary?
