TLS Certificates (Inbound)

smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
      smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key

  • These are default self-signed certificates.

  • They are included for completeness but are not actively used because inbound TLS is disabled.
