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 multicom_tool...@sysbio.rnet.missouri.edu. 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: multicom_tool...@sysbio.rnet.missouri.edu 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.
