Hello, Hope that you could give me some instructions and advice. Thank you very much!
Problem: I run postfix on sysbio.rnet.missouri.edu (Red hat 4.1.2-50). I create a mailing list named [email protected]. After subscribing to this list, I receive the confirmed and welcome email. I send a message to this list. About one day after sending, I receive an email (as follows): Delivery has failed to these recipients or groups: [email protected] The server has tried to deliver this message, without success, and has stopped trying. Please try sending this message again. If the problem continues, contact your helpdesk. Postfix configure: #soft_bounce = no mail_owner = postfix #myhostname = host.domain.tld #myhostname = virtual.domain.tld #mydomain = domain.tld #myorigin = $myhostname #myorigin = $mydomain inet_interfaces = localhost mydestination = $myhostname, localhost.$mydomain, localhost unknown_local_recipient_reject_code = 550 alias_maps = hash:/etc/aliases, hash:/data/mailman/data/aliases alias_database = hash:/etc/aliases recipient_delimiter = + debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin xxgdb $daemon_directory/$process_name $process_id & sleep 5 setgid_group = postdrop
