Postfix is a SMTP server, often used on Linux. I won’t go here into details in this configuration, just a simple installation as a SMTP router. The idea is that a website can simply send emails directly.


In the install process, choose Internet site to no relay emails. Put your email address when ask for alias for root or postmaster.

If you need to change aliases later,

and once updated, issue the command

for Postfix to reload the file.

Test the configuration

You should receive the email in your regular mailbox.
