[Dovecot] dovecot as POP3 proxy

Hello,

I am trying to set up dovecot as pop3 proxy.

There is net lines in my auth section:

    passdb passwd-file {
            args = /usr/local/etc/dovecot/proxy.users
    }

    userdb static {
            args = uid=26 gid=6
    }

File proxy.users should contain a list of users. Now it looks like test:::::::proxy host=10.10.10.10

and everything is OK.

My question is how to change passwd-file in order to match any username? I need something like *:::::::proxy host=10.10.10.10

Thanks in advance!
