No. The outgoing headers include enough reply information for misdelivery to cause bounces to go into the ether, or to my ISP (_postmaster_ or suchlike at my ISP, not _me_) that this is the wrong approach. It is necessary that the first _mail_system_ that handle things be a valid standalone domain for this reason. So either one needs one's own domain and a full setup on the home box, or one needs to deliver directly to the ISP's SMTP service. -- Cameron Simpson, DoD#743 [EMAIL PROTECTED] http://www.zip.com.au/~cs/ Using encryption on the Internet is the equivalent of arranging an armored car to deliver credit-card information from someone living in a cardboard box to someone living on a park bench. - Gene Spafford
