Distribution: RedHat, Fedora, Ubuntu Posts: 344 Rep:	Quick Mail Envelope Question So in my mail envelope (I believe this info is contained within the envelope) I have this as my first received line: Received: from unknown (HELO docnotes.catholic-doc.org) (67.33.15.34) by mail-hub.123nc.com with SMTP; 17 Jun 2004 21:50:04 -0000 My question is, what is the host docnotes.catholic-doc.org role in this piece of information? I understand that you are supposed to say "helo" to an smtp server when you make a connection. Is it safe to assume that this hostname can be easily faked and should not be considered as real? And notice that it says "unknown" prior to the helo info. What should be in place of the keyword unknown? Thanks!
