RE: [cobalt-users] Setting up Qube3 as a secondary mail server

["Edward R. Milstein" <eddie@xxxxxxxxxxx>]

If the secondary is using sendmail or qmail (the two MTA's I most
understand), they will recognize they are secondary by the MX priority
and queue the mail when received.  When the MTA runs the queue the
secondary will try and deliver to the primary at that time..

Therefore there is no need to sync users or anything like that...

As far as the CNAME question, I am not sure what you mean..  You setup
the primary and secondary using MX records, not CNAMES...

It will look something like

Domainname.com in mx 10 primarymailserver.com.
Domainname.com in mx 20 secondarymailserver.com.

Use the UI to set it up, assuming you have DNS hosted on the cobalt
box..
