Just to be sure, we save a copy:
cd /etc/postfix cp main.cf main.cf.org
Now we edit the file main.cf:
The following lines need to be changed:
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
change to
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.1.0/24
Obviously you add your internal network, 192.168.1.0 is a good guess (192.168.0.0 is another much used one).
If you don't do this, then your bubba won't accept mail for relaying.
relayhost =
change to
relayhost = [smtp.gmail.com]:587
Add the following lines:
smtp_tls_CAfile=/etc/ssl/certs/ca-certificates.crt smtp_use_tls=yes smtpd_sasl_local_domain = $myhostname smtp_sasl_tls_security_options = noanonymous smtpd_sasl_application_name = smtpd
Now create or edit the file sasl_passwd and add the following line with your gmail account data:
[smtp.gmail.com]:587 Your_Gmail_ address:Your_Gmail_password
save it and run
postmap sasl_passwd
to (re)generate the sasl_passwd.db file.
Now restart postfix
/etc/init.d/postfix restart
Look at /var/log/mail.log
tail -f /var/log/mail.log
and send an email using your bubba (b3) as smtp server.
