I was wondering if the email send from FreePBX is encrypted? I am particularly interested in email notification of received Faxes.
I use Gmail as my SMTP provider. I looked at /etc/postfix/main.cf and at the end it says:
readme_directory = /usr/share/doc/postfix-2.10.1/README_FILES
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_sasl_type = cyrus
smtp_use_tls = yes
smtp_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt
relayhost = smtp.gmail.com:587
myhostname = nameofmydomain.com
mydomain = nameofmydomain.com
myorigin = nameofmydomain.com
I think based on this information that the email transmission is encrypted but appreciated reassurance.
