Welcome to the club!
My images might not come through but here is the alert setup that worked for me.
I am using the default alerts till I am better at using the new alerts. I wrote options for both.
Set the enable to false. When it is set to true it enables the old alert system.
The old alert system works but it sends a lot of weird reports sometimes. Stuff isn’t needed.

> <adama@memetic.org>";

You would need to use postfix to relay mail.
Then I need to set the sysContact in all devices. That with the SmartHost should give me alerts.
I just re-installed PostFix as a smarthost following the below:
http://gopalthorve.com/install-postfix-mta-and-configure-smarthost/
For an domain name I used purafilter2000.com.
I used svr-exchange.purafilter2000.com here.
Postfix Config File:
myhostname = network-monitoring
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = purfilter2000.com, network-monitoring, localhost.localdomain, localhost
relayhost = svr-exchange.purafilter2000.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/smarthost_passwd
smtp_sasl_security_options = noanonymous
I creaded a username/password file as the guide suggested.
Purafilter2000.com itadmin@purafilter2000.com:[admin pass]
I secured thefile and enabled permissions for root.
When it is set to false it enables the new alert system.
In the new alert system you must setup alerts in the Observium GUI.

Subject: [Observium] Help with a simple email setting
Sorry if this has been posted before but I have been trying to find it for a few hours now.
I'm trying to find where the system sets the emailto field when hosts go down.
Right now, when a host goes down, somehow its still emailing the old email address sometimes. I have grep -R the entire /opt/observium folder but nothing comes up. I have also tried to set the following setting to no avail
$config['alerts']['email']['enable'] = TRUE;
$config['alerts']['email']['default'] = "netops@blah.com";
$config['alerts']['alerter']['default']['descr'] = "Default Email Alert";
$config['alerts']['alerter']['default']['type'] = "email";
$config['alerts']['alerter']['default']['contact'] = "netops@blah.com";
$config['alerts']['alerter']['default']['enable'] = TRUE;
But sometimes some of the emails(not all) will still go out to our old email address help@blah.com
I cant for the life of me figure out how to fix it and have been scouring the observium docs to no avail.
Any help would be most appreciated.
Thanks!
