The other day I configured my sendmail to masquerade as a known domain and was able to send messages without any trouble. However I received a surprise on Monday when I went to the university and had about 5 messages from the system admin in my mailbox: it seems that a large quantity of my messages had bounced and she had received the error messages. More of less what happens is this: my box sends out the message through the university's POP3 server, masquerading as iname.com (DMiname.com). But when the message tries to get through the other servers don't see me as iname.com, they see me as mario.ti2dll.net which is the hostname I have programmed. Since it doesn't exist they bounce the message and since the bounced message can't get back to the sender @ mario.ti2dll.net it bounces to postmaster at the local machine. How do I prevent this from happening? Must I change my hostname to something that exists? Unfortunately I forgot to save the error message my admin sent to me :) >From what I was able to find in my received folder it was something like this: > Date: Thu, 15 Oct 1998 08:03:37 -0600 > From: Mail Delivery Subsystem <[EMAIL PROTECTED]> > To: [EMAIL PROTECTED] > Subject: Postmaster notify: Host unknown (Name server: mario.ti2dll.net: host not >found) > > The original message was received at Thu, 15 Oct 1998 08:03:35 -0600 > from localhost > > ----- The following addresses had permanent fatal errors ----- > <[EMAIL PROTECTED]> > > ----- Transcript of session follows ----- > 550 <[EMAIL PROTECTED]>...
