Hello, I'm trying to get postfix and mailman going on CentOS 5.4. I had this working previously, six to eight months ago, and shut it down since the need for use was no longer there. I've now reactivated mailman and set up a list. The software versions I'm using are httpd 2.2.14, postfix 2.3.3, and mailman 2.1.9. All the services are started, the list is created, and email is sent to the list owner. The problem is reply addresses for subscriptions are being sent to mailman@domain.com rather than mailman@lists.domain.com as i want. In the email all the email addresses point to mailman@lists.domain.com except for the reply to header that goes to as i said mailman@domain.com. The lists.domain.com is a subdomain dedicated to the mailing list.The mailman newlist command correctly creates list aliases in /etc/mailman/aliases file. Any ideas? Thanks. Dave.
