X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 16 Mar 2008 07:47:19 -0000 The send-pr appears to assume that mail can and will be sent directly through sendmail or equivalent rather than inderctly through an ISP mail service. I can certainly successfully send mail directly via sendmail but as I don't have a static IP address or a registered name the (bogus?) name used is not able to be validated. So when I send-pr I get a returned mail message which includes the following: ----- The following addresses had permanent fatal errors ----- (reason: 450 4.7.1 : Helo command rejected: Host not found) It seems most destinations are not so pedantic and accept the (bogus) name. Now if I set up sendmail with some registered name in place of mail.whatnot.on.net then I believe the message will be accepted. So the question is would it be legitimate or fraudulent to set sendmail to work with the name of my ISP's mail server in the Helo command -- after all this is the rout that will be followed by any responses. Is there a better way around the difficulty. Views please Malcolm Kay
