There is no general solution for this problem. In the absence of a To:, 
Cc: or other header indicating who the message was delivered to, 
fetchmail has to guess or be told which user the mail is for. The POP3 
protocol provides no way of indicating this information to fetchmail.

Some ISPs will add a "Delivered-To:" or equivalent header than can be 
used, but that's up to the ISP. Other ISPs will allow you to set up 
multiple separate mailboxes for different users. But shared POP3 
mailboxes are going to exhibit this problem and there's not a lot you 
can do about it.

See http://www.catb.org/~esr/fetchmail/fetchmail-man.html#25 for a more 
detailed discussion on this.
