I have Postfix with SMTP AUTH with self issued certificate, all works well when a remote Outlook or Thunderbird attempts to use it, it get's a dialogue like;
'security certificate can not be verified' what file(s) do I need to provide to remote mail clients to suppress the warning ? do I simply provide 'raw' file(s) from /etc/postfix/tls ? do the Outlook/Thunderbird users then import this file ? ---- smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous smtpd_tls_CAfile = /etc/postfix/tls/cacert.pem smtpd_tls_auth_only = yes smtpd_tls_cert_file = /etc/postfix/tls/smtpd.crt smtpd_tls_key_file = /etc/postfix/tls/smtpd.key smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_security_level = may smtpd_tls_session_cache_database = btree:/var/spool/postfix/smtpd_tls_session_cache smtpd_tls_session_cache_timeout = 36000s ---- -- Voytek
