 Most installs are probably using postfix, certainly all of mine are.
 
 Are you *sure* your config option is the correct one?

 If the default is working, why not just use that?

 CAMERON have you checked that the email is not being captured by the
 spam filter?
 
 I'm asking because associating the contact with the alert worked for
 me.. I can now see that postfix is sending mail to my contact email
 address..
 
 my problem, and maybe Cameron, is that the from filed still is from
 root@observium01 which is being banned in my spam filter. I can't
 whitelist it because it has to be a propper domain syntax to do so..
 like root@observium01.org or something like that..
 
 I know that tom said it was the default from field from postfix and
 not the actual from field but i do see a root@observium01 in my spam
 filter that is being blocked... so something is wrong..

 Now im happy with only one email for alerting so i could go with
 configuring it in the config.php file.. but nothing will work aslong
 as the from field is from root@observium01
 
 I really don't care what is in the from field as long as its propper
 syntax. I would just whitelist it... its somewhat of a stupid
 problem actually :)
