Command - LIST
Usage   - LIST
          LIST range

Lists memos in the range range that people have sent you.
You can read them with the READ command.  Memo's marked with
"*" are new, and those with "D" are flagged to be deleted.
Use the PURGE command to delete memo's that's flagged to be
deleted.  To limit flooding, LIST will only show the first
20 entries in range.

Example:
   LIST
   LIST ALL
   LIST 1-10,40-
