archiving rules

[Nerijus Baliunas]

Hello,

I have Non Spam Actions = %rules-dir%/archive-nonspam.rules
and archive-nonspam.rules is:

To:         *@domain.lt      deliver header "X-Spam-Status: No" forward _TOUSER_ at backup.domain.lt
From:       *@domain.lt      deliver header "X-Spam-Status: No" forward _FROMUSER_.Sent at backup.domain.lt
FromOrTo:   default       deliver header "X-Spam-Status: No"

Messages are archived correctly. The problem is, when the message is sent like this:
To: user1 at externaldomain.lt
Cc: user2 at domain.lt

The message is sent to both user1 at backup.domain.lt and user2 at backup.domain.lt.
Is it possible _TOUSER_ in above rule to be used only if recipient domain is local, i.e. domain.lt?

Regards,
Nerijus
