These options are set in installation scenarios of translate5

Normal options are set in the database table Zf_configuration.

In contrast, installation specific options are set in the file

/application/config/installation.ini

which resides in your translate5 installation directory. If you followed translate5 Ubuntu installation manual, your installation directory is located at

/var/www/translate5

If you used translate5 windows installer, it is located at

c:\xampp\htdocs\translate5\

Options in installation.ini

• database connection information
• resources.mail.defaultFrom.email  
  => this is the default email-address of your translate5 installation
• runtimeOptions.sendMailDisabled
  => set to 1, to disable all mail sending. This is the recommended setting, if you have no mailserver installed.
  => set to 0 to enable mail sending. If you use this setting, your php-installation must know a mailserver to pass emails to.
  For your information: If you enable mails in translate5, in case of php errors translate5 will send an email about the error to the mail address configured in resources.mail.defaultFrom.email  

Be careful: Configuration values in installation.ini overwrite values set in Zf_configuration. With the exception of the above listed options this IS NOT recommended.
