DMTP server seems not finished at all

[netcom-rs]

looking at the sources, src/servers/dmtp/dmtp.c it seems that every command response is set to predefined values while doing nothing else than returning defined. Example is below. Question to @ladar : why are you advertising dark mail as secure while it is not working? Or you have another in-house version of dmtp that's not published? What is going on?

Best regards.

 * @brief	Process an DMTP MAIL command.
 * @param	con             the DMTP client connection issuing the command.
 * @return	This function returns no value.
