[Qmail-scanner-general]check subject and forward to another recipient

[Schnippo]

Hi all

Im using qmail-scanner 1.25 on a gentoo box. i need to to something really strange ;)

filter all incoming mails. if the subject contains "(R)" the mail should be forwarded to a special mailserver. i dont have problems with detecting the (R) in the subject, but how can i change the recipient. i tried to add "RCPT TO:..." to the headers. it didnt work. i may added at the wrong position. can i even do this with qmail-scanner?

thanks in advance for _any_ hints that may help!
