Re: [cobalt-users] Configuring secondary MX on RAQ.

[Craig St George <craig@xxxxxxxxxxxxx>]

Hi I have a RAQ3 as a backup server
I have MX to the normal server set high
and MX to the backup as lower

Make sure on the backup server that you have no mail records in sendmail 
for that second domain eg you do not what it
set to accept mail for the domain
make sure its not in the sendmail.cw  or that you have no catch all in the 
virtusertable

also you have to edit the sendmail.cf file
I had to change the
# privacy flags
form
O PrivacyOptions=goaway

to somthing like

O PrivacyOptions=authwarnings,novrfy,noexpn


then you restart sendmail
/etc/rc.d/init.d/sendmail restart
