Outgoing mail not encrypted

[apinto]

Try this:

Code:

# postfix config file

#...

# tls config

#CHANGE

#smtp_use_tls

= no
smtp_use_tls = yes

smtpd_use_tls = yes

#ADD
smtpd_enforce_tls = no

smtpd_tls_security_level = may
smtp_tls_note_starttls_offer = yes
smtpd_tls_loglevel = 2
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
smtp_tls_session_cache_database = btree:$data_directory/smtp_tls_session_cache
smtpd_tls_key_file = /etc/postfix/ssl/mail.johnxxxxxxgd.com.key.pem
smtpd_tls_cert_file = /etc/postfix/ssl/mail.johnxxxxxxgd.com.crt.pem
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem

#...

Also, make sure you use the following settings on Thunderbird/Mail Client:

• Server: mail.johnxxxxxxgd.com
  
• Port: 995
  
• User Name: info@johnxxxxxxgd.com
  
• Con. Security: SSL/TLS
  
• Auth: Normal Password
  

If you are using Connection Security: None (default for Thunderbird) it will always send unsecured emails.

Also, using the localhost of your server (for ex. RoundCube) it does not send the emails secured by default, and it does NOT NEED TO because SSL secures the client-server connection, if your client is inside the server it is already "secured".

Thanks for your reply.

That worked, making those two changes to the file seemed to do the trick for me.

My connections settings in thunderbird are

• Server: mail.johnxxxxxxgd.com
  
• Port: 587
  
• User Name: admin@johnxxxxxxgd.com
  
• Con. Security: STARTTLS
  
• Auth: Normal Password
  

If I change it to your suggestions I get this error "An error occurred while sending mail: The mail server sent an incorrect greeting:  +OK Dovecot (Ubuntu) ready.."



Thanks for all your help

Yah to use TLS you need another setup on master.cf
Honestly I dont even remember what I did

Glad it worked!!
