I see a problem here, too, but with a different message:
smtp-server: 550 5.1.1 <-s>... User unknown
. . . message not sent.


I also have a problem receiving mail because nail does not accept 
a mailbox account name containing "/". I have reported it to the 
author and he says he fixed it in the CVS ("upstream").

Considering the weirdness of the DOS device filenames, I would 
have done it shorter and sloppier, like auxx.c :)
