Hi!
That should work fine I think... I also think that this would work:
domain.net. IN MX 10 mail1.domain.net.
domain.net. IN MX 10 mail2.domain.net.
I wonder what will happend if one of the servers go down (hardware problems,
maintance, power outage). Will the other server handle all requests if one
have two MX-records? What happens if one add serveral IP-adresses for one
name?
Is there any way to make the NFS-server storing all the mails faulttolerant?
Is it possible to have one of the mailservers on a different
internetconnection and mount the mailstorage-server over internet? Since NFS
uses UDP, I think that NFS would fail.
Does anyone got a bomb-proof mailsystem? :)
