* to prevent command execution. escapeshellcmd prevents
* command execution, but allows to add additional parameters. For security reason,
* this parameter should be validated.
*

* that are allowed as email addresses by internet RFCs cannot be used. Programs
* that are required to use these characters mail cannot be used.
