Hi, I would disable in my postfix installation the sending of bounce mail.
I try to change my master.cf in this way: bounce unix - n n - 0 pipe -vv user=mail flags=Rq argv=/etc/postfix/bounce.sh and the script bounce.sh is: # cat /etc/postfix/bounce.sh #!/bin/bash cat > /dev/null exit 0 It works, but in my maillog i have: May 26 17:50:19 mmt-l-fl11-prv postfix/pipe[23380]: bounce socket: wanted attribute: flags May 26 17:50:19 mmt-l-fl11-prv postfix/pipe[23380]: vstream_buf_get_ready: fd 9 got 406 May 26 17:50:19 mmt-l-fl11-prv postfix/pipe[23380]: input attribute name: nrequest May 26 17:50:19 mmt-l-fl11-prv postfix/pipe[23380]: warning: unexpected attribute nrequest in input from bounce socket May 26 17:50:19 mmt-l-fl11-prv postfix/pipe[23380]: warning: deliver_request_get: error receiving common attributes May 26 17:50:19 mmt-l-fl11-prv postfix/pipe[23380]: deliver_request_final: send: "" -1 Can you point me where is the problem? And, Is there another way to disable bounce notification?
