Those are not "From:" headers, they are "Received:" headers and they are required by the SMTP standard. Each machine that handles the message must add this header. The only way to reduce their number is to simplify your mail routing. Generally, this not a problem for recipients because mail clients do not display this header by default. Some MTAs are configured to bounce messages that have too many of these headers (sendmail defaults to 30, I think) because that might indicate a mail loop. These headers are there to simplify mail troubleshooting. A mail admin can see where the message went, and when. My recommendation is to leave this alone unless you have a real operational reason to go into the source code of your MTA and change it. Tony - -- Anthony E.
