pop3d+maildirpath

Hi,

I have a postfix mail server on my linux with
mysql,sasl,courier-imap&postfixadmin. I can send emails but no receive.
Postfix admin create a folder for user /usr/local/virtual/user@domain, the
emails landing in this place in the ‘new’ folder. In pop3d I have that
MAILDIRPATH=Maildir, when I change this location to
MAILDIRPATH=/usr/local/virtual/user@domain I can receive emails. Ho to
change this location to universal path, maybe is possible to apply some
variable %username or something like that?

Best regards
Sebastian
