# cd /etc/dovecot/conf.d # nano 10-ssl.conf

ssl = yes

ssl_cert = </home/teo-en-ming-corp/2023.crt ssl_key = </home/teo-en-ming-corp/2023.key ssl_ca = </home/teo-en-ming-corp/inter2023.crt

# nano /etc/dovecot/dovecot.conf

protocols = imap pop3 !include conf.d/*.conf

SECTION ON POSTFIX

# nano /etc/postfix/main.cf

smtpd_use_tls = yes smtpd_tls_auth_only = yes smtpd_tls_key_file = /etc/postfix/2023.key smtpd_tls_cert_file = /etc/postfix/chain2023.crt smtpd_tls_CAfile = /etc/postfix/inter2023.crt

# nano /etc/postfix/master.cf

submission inet n - n - - smtpd smtps inet n - n - - smtpd tlsmgr unix - - n 1000? 1 tlsmgr

That's all.
