2) The "Save Settings as Default" button will write the settings to the file SendSMTP.ini in the same path as the SendSMTP.exe file. Any text in the Body field will be saved to the SendSMTPBody.rtf file in the same path.
3) You can create multiple INI files and accompanying Body files if you wish. Use the switch /S to specify the INI file (and hence the Body) you want to use.
4) You can double click on the version number in the About dialog box to activate and disable debugging.
5) When using the /PASSX switch, the encrypted password can be copied from the SendSMTP.ini file if the password is used in the current settings.
