Hmmmm....... the fact that the headers are ending up in the body tells me that qmail sendmail isn't looking for the headers. Instead of using for instance /usr/sbin/sendmail try /usr/sbin/sendmail -t

The -t switch tells qmails sendmail to look for those headers. I use qmail also but haven't gotten around to the mail customizations of Links SQL yet. Will probably have the same troubles once I do though.... :-)

Hope that helps,
