Hi. I am trying to get notification set up for nagios and in order to do that I have installed Postfix on the ubuntu server. I would like to either relay the email through our local exchange server or gmail (whichever is easier to configure on the linux side). I have gone through numerous tutuorials, etc but everytime I try to enter half of the commands (i.e.sudo postmatp hash:/etc/postfix/sas_password or even mailq) i get the error below.
postmap:fatal: bad string length 0 < 1:setgid_group =
I am lost and just want to get the these nagios email notifications working..Someone please help : )
