I'm using this online guide here to enable simple mail sending from linux (ubuntu) terminal with postfix through some gmail account. I've done the steps listed there:
sudo apt-get install postfix mailutils libsasl2-2 ca-certificates libsasl2-modules
vim /etc/postfix/main.cf
And add these lines:
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_tls_CAfile = /etc/postfix/cacert.pem
smtp_use_tls = yes
Then edit this file:
vim /etc/postfix/sasl_passwd
To add the lines like it says in the guide:
[smtp.gmail.com]:587 USERNAME@gmail.com:PASSWORD
(Of course with my own mail and password) then finally:
sudo chmod 400 /etc/postfix/sasl_passwd
sudo postmap /etc/postfix/sasl_passwd
And then:
sudo /etc/init.d/postfix reload
When I try to send a simple mail nothing happens:
echo "Test mail from postfix" | mail -s "Test Postfix" you@example.com
(Of course here too with some other valid email)
What am I doing wrong? Thanks!
I think you need validate certificates to avoid running into error.
Try with:
cat /etc/ssl/certs/Thawte_Premium_Server_CA.pem | sudo tee -a /etc/postfix/cacert.pem
If you run into issues with above command, try rename the certificate to:
thawte_Primary_Root_CA.pem in above command.
And now, reaload the server
sudo /etc/init.d/postfix reload
