Try sending output from: postfix status mailq Try telnetting to your smtp server and sending a message like this from the local system: substitute a valid user/domain on the mail from line and a valid email address in your domain on the rcpt to line. Do this, logged onto the mailserver. telnet localhost 25 helo mydomain.com (substitute a valid domain here) mail from: <someuser at validdomain.com> rcpt to: <youremailaddress at yourdomain.com> data From: someuser at validdomain.com to: youremailaddress at yourdomain.com subject: test This is a test mesage . note: blank line between mail headers and body end data with line containing only '.'. Then check your maillog and send the output to the list. Nataraj postfix status: postfix/postfix-script: the Postfix mail system is running: PID 5936 mailq: Mail queue is empty Did the telnet localhost 25, it answered but not sure I understood you what I needed to do. Thanks!!
