| + | ===== Relay Authentification ===== | ||
| + | If your relay host requires authentication, or blocks port 25, you'll need to further configure Postfix: | ||
| + | |||
| + | <code> | ||
| + | apt-get install libsasl2-modules | ||
| + | </code> | ||
| + | |||
| + | <code> | ||
| + | postconf -e "relayhost = [smtp.domainname.tld]:587" | ||
| + | postconf -e "smtp_sasl_auth_enable = yes" | ||
| + | postconf -e "smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd" | ||
| + | postconf -e "smtp_sasl_security_options = noanonymous" | ||
| + | </code> | ||
| + | |||
| + | Create a file called sasl_passwd in// /etc/postfix/sasl_passwd//. Inside type in | ||
| + | <code> | ||
| + | sudo nano /etc/postfix/sasl_passwd | ||
| + | |||
| + | [smtp.domainname.tld]:587 username@domainnanme.tld:mypassword | ||
| + | </code> | ||
| + | |||
| + | Now change permissions so others can't read it: | ||
| + | <code> | ||
| + | chmod 600 /etc/postfix/sasl_passwd | ||
| + | </code> | ||
| + | |||
| + | Now postmap it. (It creates a database-like file so postfix can read it.) | ||
| + | <code> | ||
| + | postmap /etc/postfix/sasl_passwd | ||
| + | </code> | ||
| + | |||
| + | Restart postfix | ||
| + | <code> | ||
| + | postfix reload | ||
| + | </code> | ||
| + | |||
| + | Done. You can use "mutt" to send emails outside. Check /var/log/mail.log to see if everything is working. | ||
| ===== Test Postfix ===== | ===== Test Postfix ===== | ||
| + | You should nbow be able to send mail to the outside world using Postfix: | ||
| + | <code> | ||
| + | telnet localhost 25 | ||
| + | </code> | ||
| + | |||
| + | You should see: | ||
| + | <code> | ||
| + | Trying 127.0.0.1... | ||
| + | Connected to localhost.localdomain. | ||
| + | Escape character is '^]'. | ||
| + | 220 server1.example.com ESMTP Postfix (Debian/GNU) | ||
| + | </code> | ||
| + | |||
| + | Send an email to a test recipient: | ||
| + | <code> | ||
| + | mail from:<you@youremail.com> | ||
| + | rcpt to:<user@example.com> | ||
| + | data | ||
| + | To: user@example.com | ||
| + | From: you@youremail.com | ||
| + | Subject: Hey my first email | ||
| + | This is my first email on debian postfix after installing configuring it. | ||
| + | It was easy. | ||
| + | </code> | ||
| + | |||
| + | To end data hit enter, type in a dot, and hit enter again: | ||
| + | <code> | ||
| + | . | ||
| + | </code> | ||
| + | |||
| + | Quit the session: | ||
| + | <code> | ||
