# mkpop3dcert

## Name

mkpop3dcert -- create a test SSL certificate for POP3 over SSL

## Synopsis

/usr/sbin/mkpop3dcert

## DESCRIPTION

POP3 over SSL requires a valid, signed, X.509 certificate. The default location for the certificate file is `/usr/share/pop3d.pem`. mkpop3dcert 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/share/pop3d.pem` must be owned by the root user and have no group or world permissions. The mkpop3dcert command will enforce this. To prevent an unfortunate accident, mkpop3dcert will not work if /usr/share/pop3d.pem already exists.

mkpop3dcert requires `OpenSSL` to be installed.

## FILES

/usr/share/pop3d.pem

  X.509 certificate.

/etc/courier-imap/pop3d.cnf

  Parameters used by OpenSSL to create the X.509 certificate.
