FreePBX Postfix configuration

Hi everyone, I’m trying to configure postfix to send emails with port 465 but I’m literally going crazy. These are my log errors:

Jul 8 16:47:02 centralino postfix/smtp[15525]: CLIENT wrappermode (port smtps/465) is unimplemented

Jul 8 16:47:02 centralino postfix/smtp[15525]: instead, send to (port submission/587) with STARTTLS

sasl_passwd file:

[]:465 [email protected]:PASSWORD file:

relayhost = []:465

smtp_use_tls = yes

smtp_tls_wrappermode = yes

smtp_tls_security_level = encrypt

smtp_tls_CAfile = /etc/ssl/certs/ca-bundle.crt

smtp_sasl_auth_enable = yes

smtp_sasl_security_options = noanonymous

smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd

smtp_sasl_tls_security_options = noanonymous

smtp_sasl_mechanism_filter = login

someone can help me?

From what I understand, the FreePBX iso automatically installs Postfix 2.10.1, while to use TLS with port 465 you need Postfix 3.0. Do you know a way to update postfix without breaking FreePBX?
