TheWebalyst: I got this working by changing the sasl_passwd setting (working version below). It is not clear if Albert's "Work in progress" was working or not, but the sasl_passwd setting did not work for me, and appeared to be incorrect so following these instructions should now work.
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).
(TheWebalyst: Alternatively, if you want to send from all machines on your network and can't get the above working, comment out the mynetworks value with a '#' and insert "mynetworks_style = subnet" instead.)
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 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.
Redirecting Email for Bubba and Users
Now your bubba can send mail to the world via gmail (as well as acting as an SMTP relay for your network) you might want mail sent to b3 users to end up elsewhere.
I found two postfix settings useful for this, although I (TheWebalyst) admit some ignorance about the ways you can do this.
always_bcc = email_address
Causes copies of certain system mails to be sent to the specified address.
Perhaps more useful, you can avoid having to read mail on b3 by redirecting mails for individual accounts. This Involves the follosteps:
1) Create a relocation map file: /etc/postfix/relocation which contains one line for each redirected user account as follows:
username email_address
2) Edit /etc/postfix/main.cf and add the following entry:
relocated_maps = hash:/etc/postfix/relocated
3) Generate the map (failure to do this can stop postfix working!) as follows:
postmap /etc/postfix/relocated
4) Restart postfix:
/etc/init.d/postfix restart
Note: if you edit /etc/postfix/relocated you need to rebuild the map database with "postmap /etc/postfix/relocated".
