Secure ESMTP requires a valid, signed, X.509 certificate. The default location for the certificate file is
/usr/lib/courier/esmtpd.pem. The
mkesmtpdcert
generates a self-signed X.509 certificate, mainly for testing. For production use the X.509 certificate must be signed by a recognized certificate authority, in order for mail clients to accept the certificate.
/usr/lib/courier/esmtpd.pem
must be owned by the daemon user and have no group or world permissions. The
mkesmtpdcert
command will enforce this. To prevent an unfortunate accident,
mkesmtpdcert
will not work if
/usr/lib/courier/esmtpd.pem
already exists.
mkesmtpdcert
requires OpenSSL to be installed.
