I didn't catch this before I posted my last article. Site-stripping would be done when somebody does a "reply" to a news article, but their reply software can't make use of the From: or Reply-to: fields. These replies must therefore be sent out along the Path: line, which is gross. Therefore, to minimize the path, the reply software would strip out all sites in between the first and last domain addresses in the Path: line. This implies that only sites with smart (class 3 or similar) mailers would identify themselves with their domain name in the Path: line. The Received/Sent-by stuff has to do with the information which must be lost whenever mail goes through a site which runs sendmail. Sendmail can't keep the ">From site remote from nextdoor" lines which are added once per uucp hop. A site which uses sendmail must be fed the incoming mail with all these multiple >From lines crushed into a single line. This means the timestamp information left by each site is lost. I suggested converting these individual >From lines into Received: lines just to save the timestamp. -- Hokey ..ihnp4!plus5!hokey 314-725-9492
