Mail server

Configuring a mail server involves two aspects:

  • 📩 Sending mails
  • 📨 Receiving mails

To avoid having our emails marked as spam, we have to properly configure our mail server and DNS records.

You can send emails after configuring an MTA using:

$ sudo apt install mailutils
$ echo "body" | mail -s "subject" email

Postfix

Postfix (0.4k ⭐) is a well-known MTA.

$ sudo apt install postfix
$ sudo nano /etc/postfix/main.cf
# edit those lines to match:
# inet_interfaces = loopback-only
# mydestination = $myhostname, localhost.$mydomain, $mydomain
$ sudo systemctl restart postfix
