.SH "NAME"
mkesmtpdcert \- Create a secure SMTP test certificate
.SH "SYNOPSIS"
.HP \w'\fB/usr/sbin/mkesmtpdcert\fR\ 'u
\fB/usr/sbin/mkesmtpdcert\fR
.SH "DESCRIPTION"
.PP
Secure ESMTP requires a valid, signed, X\&.509 certificate\&. The default location for the certificate file is
/usr/lib/courier/esmtpd\&.pem\&. The
\fBmkesmtpdcert\fR
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\&.
.PP
/usr/lib/courier/esmtpd\&.pem
must be owned by the courier user and have no group or world permissions\&. The
\fBmkesmtpdcert\fR
command will enforce this\&. To prevent an unfortunate accident,
\fBmkesmtpdcert\fR
will not work if
/usr/lib/courier/esmtpd\&.pem
already exists\&.
.PP
\fBmkesmtpdcert\fR
requires OpenSSL to be installed\&.
