Generally to setup postfix to relay to Gmail, the first thing you need to do is edit your <code>/etc/postfix/</code> file to include: <pre> relayhost = []:587 smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous smtp_tls_CAfile = /etc/ssl/certs/Equifax_Secure_CA.pem smtp_use_tls = yes </pre> Then you need to set your gmail password and address in <code>/etc/postfix/sasl_passwd</code> like so: <pre> []:587 </pre> Now make sure it’s permissions are correct and update it with: <pre> sudo chmod 400 /etc/postfix/sasl_passwd sudo postmap /etc/postfix/sasl_passwd </pre> And finally, restart postfix with: <pre> sudo service postfix restart </pre>

In your specific case, since you can’t telnet to <code> </code> it sounds like you might have your SMTP port blocked. This happens in some specific cases in order to fight against spam. Please open a support ticket, and the team should be able to help you get that fixed:
