This is because many email servers will check whether you have a valid rDNS.

has address 192.0.43.10ġ0.43.0. domain name pointer Īlthough it could resolve to a different hostname, just as long as the domain is the same. First edit the/etc/default/monit file and make sure startup is set to 1, so it starts on boot. Important, in order to improve deliverability you want to make sure that your IP address has a reverse DNS record that resolves back to your domain.įor example, if your domain is and your server is then it should resolve something like this: host d/monit start sudo monit sudo monit start all sudo monit status. If you have a service with an existing /etc/init.d script, you can use this cookbook to create a Monit configuration file to monitor that service. Now when you configure monit as described above you will be able to send out email. Launching and monitoring a process with an existing init. You will now have configured postfix to send and receive email to and from the internet.

Or you can use a remote smarthost/gateway.Įdit: brief explanation how to install postfix How you set up and configure the MTA is out of the scope of this question, however if you want it to send mail directly it would be best to have a static IP, rDNS and mx records. In that case monit will hand off the email delivery to an actual MTA who can then take care of sending it out, the MTA is perfectly capable of dealing with the remote server being unavailable, unlike monit (since it's not made for that). What I would suggest is to just install a local MTA to listen on 127.0.0.1 and then configure monit like this: set mailserver 127.0.0.1 Monit is a free open source and very useful tool that automatically monitors and manages processes, files, directories, checksums, permissions, filesystems, and services like Apache, Nginx, MySQL, FTP, SSH, SMTP, and so on in a UNIX/Linux based systems and provides an excellent and helpful monitoring functionality to system administrators. Even if you do have an account monit isn't the best program to deal with submitting email. You can not configure some other company's email server to hand off emails unless you have an actual account there.
