It is important to get email alerts when a trigger happens in Zabbix. If you don't already have an SMTP server for sending emails, you can also install a Send Only server on the Zabbix Server itself.

The commands in this lecture are

$ sudo apt install mailutils

A postfix config screen should appear,

select 'internet site'

enter the mail servers name, it should be something you've already setup in your existing DNS providers name server elsewhere.

For example. I pre set up an A name record for smtp.seanwasere.com and it points to the IP Address of the this Zabbix Server.

Then configure postfix by calling

$ sudo nano /etc/postfix/main.cf

scroll to the bottom, and change 'inet_interfaces = all' to 'inet_interfaces = loopback-only'

restart postfix

$ sudo systemctl restart postfix

try sending an email from the command line,

$ echo "This is the body" | mail -s "This is the subject" -a "FROM:[senders address]" [your personal email]
