Configure Postfix To Use Gmail Smtp On Ubuntu 685a2a

Configure Postfix to Use Gmail SMTP on Ubuntu Ref: https://stackoverflow.com/questions/48733960/configure-postfix-to-use-gmail-smtp-on-ubuntu Ask Question 10

I'm using ​this online guide here​ to enable simple mail sending from linux (ubuntu) terminal with postfix through some gmail . 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__maps = hash:/etc/postfix/sasl_wd smtp_sasl_security_options = noanonymous smtp_tls_CAfile = /etc/postfix/cacert.pem smtp_use_tls = yes

Then edit this file: vim /etc/postfix/sasl_wd

To add the lines like it says in the guide: [smtp.gmail.com]:587 [email protected]:

(Of course with my own mail and ) then finally: sudo chmod 400 /etc/postfix/sasl_wd sudo postmap /etc/postfix/sasl_wd

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" [email protected]

(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__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

Yes it works!! I've used: thawte_Primary_Root_CA.pem ... Thanks a lot! – ​OrenIshShalom​ ​Mar 24 '18 at 18:10
