when i try to use send myself mail from my isp's pop server, I get an error message saying.. ------------------------------------------------------ This is a collection of reports about email delivery process concerning a message you originated: <smtp linuxnet.yi.org [EMAIL PROTECTED] 99>: ...\ <<- RCPT To:<[EMAIL PROTECTED]> ->> 554 <[EMAIL PROTECTED]>: Recipient address rejected: Relay access denied Reporting-MTA: dns; mail.one.net Arrival-Date: Mon, 22 Nov 1999 20:28:31 -0500 Original-Recipient: rfc822;[EMAIL PROTECTED] Final-Recipient: RFC822;[EMAIL PROTECTED] Action: failed Status: 5.1.1 (No acceptable recipients given) Diagnostic-Code: smtp; 554 (<[EMAIL PROTECTED]>: Recipient address rejected: Relay access denied) Remote-MTA: dns; linuxnet.yi.org Last-Attempt-Date: Tue, 23 Nov 1999 10:03:58 -0500 ------------------------------------------------------ It is my understanding mandrake 6.1 uses postfix. W/RHAT, all i did was add Cwlinuxnet.yi.org to /etc/sendmail.cf Now i'm clueless and don't know why i cannot recieve mail on my box. I've even tried adding myhostname variable to /etc/postfix/main.cf to no evail. Any suggestions would be greatley appreciated. bob from cincy
