Forwarding in maildrop

Im sure this is trivial but I tried to look through the archives but they
dont seem to be working. We are running Courier-IMAP with vpopmail and qmail.
Under one user's mailfilter file I have the following:

# Forward all offsite
if (!/^X\-Loop: mail\.bway\.net/)
{
        # Add custom header first
        xfilter "reformail -a'X-Loop: mail.bway.net'"
        to ! user@xxxxxxxxxx
}

The idea is to add a header to prevent mail loops.

Is this the right way to forward email? We dont use sendmail so Im
wondering if this is indeed correct?
