Blank lines and lines with "#" in initial position are ignored. "__SENT__" is the name for the sent folder. If you leave it out, the program is fine. If you include it, the program does not try and print unread messages from it or anything, but scans it in order to see if messages in other folders are replies to messages you have sent. These boxes are listed in program output in the order listed in the config file.
Note: By default, messages that are replies to one you sent will be bolded with escape codes. To disable this, set the compile time flag STATMBX_DO_BOLD to 0
