I had this same impression but put it on account of my non-anglophone origin. Anyway, if one CC/BCC a sent message to self I think using a Noticeboard as destination folder would overcome (in part) this "fault".
Messages sent to a Noticeboard add a Noticeboards: header which will handle the Recipient's address. So, a message sent to say PM-WIN@bama.ua.edu and BCCed to a Noticeboard will have added a header Newsgroups: Pegasus Mail for Windows Discussion List <PM-WIN@bama.ua.edu>.
What I did is editing Wpm-Char.r header_strings reader_headers section to accommodate the new header (see below) and then recompile it with ResCom.exe. The resulting Wpm-Char.rsc file is put my Mailbox folder but I think it can stay at winpm-32.exe directory as well.

 This workaround won't help with the noticeboard pane which will show only the From: header, that is YOU, but once opened the message will show the proper addressee(s).
 Of course the Copyself folder is the best place to deal with sent messages, but a number of users have been using to CC/BCC themselves to keep a copy of their full blown sent messages (text + graphics + attachments, etc.) I found that Noticeboards is the best way to handle this specially because this addressee(s) thing. I'm attaching a copy of my Wpm-char.r file renamed to Wpm-char.txt to comply with forum rules.
