Usually your MDA may have this problem, so the aproach may be:
	auth-virtual-mail-user: nobody
	auth-virtual-mail-group: mail

and configure your MDA to write mailboxes 660.

As only username and password fields are used you can use new /etc/shadow
format or /etc/passwd format (as they have the same number of fields), I
named it shadow to note that you can have a passwd file readable by your
MTA/MDA user and a shadow one readable by your tpop3d user.

Of course, if you find it useful.
