 "How do you setup cobalts to act as secondary mailservers?"

www.mailfail.co.uk
uses 2 raqs for secondary/tertiary mx
2 diff datacentres
2 diff bandwidth providers

a domain is setup mx 
high - www.domain.com
low mailfail1.othellotech.net
verylow mailfail2.othellotech.net

on mailfail1 and 2 add "relay for this domain" in gui
*dont* add the domain in vsites on either

mail gos as normal, when high mx is down, queues on mailfail1, if that geos
down , queues on mailfail2
mailfail1 comes back up sendmail on mailfail2 "pushes" the mail to the next
highest available mx (mailfail1)
when the domain comes back up sendmail on mailfail1 "pushes" the mail to the
next highest available mx (domain)

Simple ;)

Does get *lots* of traffic - some customers have *crap* servers, so we queue
a lot of their mail regularly - used to charge for the traffic, but it was a
nightmare, so went for a flat fee.

There goes our business plan .....
