##Configure Postfix for Gmail SMTP## ###Edit file /etc/postfix/main.cf###
sudo vim /etc/postfix/main.cf
and add in the following to the bottom of the file:
relayhost = [smtp.gmail.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_sasl_mechanism_filter = plain
smtp_use_tls = yes
###Generate sasl_password if not already exists###
sudo vim /etc/postfix/sasl_passwd
and enter in the following:
[smtp.gmail.com]:587 [email protected]:password
Run the following commands
sudo chmod 600 /etc/postfix/sasl_passwd
sudo postmap /etc/postfix/sasl_passwd
sudo launchctl stop org.postfix.master
sudo launchctl start org.postfix.master
And you are done….
###Test your configuration### Now, you should be able to send emails from within the command line e.g. to send the contents of a directory as a tree to an email address
echo "This is a test" | mail -s "Test email from PostFix" [email protected]
