[imp] showing sender not recipient in sent-mail folder

[dadirtyluk]

hello!

i'm using head and i just saw that imp was showing the sender (which is
always the same...) and not the recipient in the folder listing!

very strange, since it's not that way for all users 8( 

haven't found any differences for these users or settings to avoid 
this, so i'm asking the list for help...

server is imapd on suse linux 7.2 :P

server => localhost
protovol => imap/notls
port => 143
folders => mail
maildomain => foo.com


any ideas??? tia luk
