Version: 2.1.15 Yum installed on CENTOS 7 Postfix

This was working on an older server that I retired because the OS had reached EOL. I cannot seem to get it to work on the new server. I went through the troubleshooting steps that applied.

An email to my list abc@xyz.co <mailto:abc@xyz.co> does not get distributed to members of the list. A look at maillog shows:

Sep 25 22:37:20 personal2 postfix/smtpd[13113]: connect from mail-qk0-x22e.google.com[2607:f8b0:400d:c09::22e] Sep 25 22:37:21 personal2 postfix/smtpd[13113]: 03AE7177B: client=mail-qk0-x22e.google.com[2607:f8b0:400d:c09::22e] Sep 25 22:37:21 personal2 postfix/cleanup[13146]: 03AE7177B: message-id=<0A56C786-DC31-42C7-8791-8595FAE7B3AE@conjelco.com> Sep 25 22:37:21 personal2 postfix/qmgr[3822]: 03AE7177B: from=<weinstoc@gmail.com>, size=2737, nrcpt=1 (queue active) Sep 25 22:37:21 personal2 postfix/smtpd[13113]: disconnect from mail-qk0-x22e.google.com[2607:f8b0:400d:c09::22e] Sep 25 22:37:21 personal2 postfix/local[13147]: 03AE7177B: to=<abc@xyz.co>, relay=local, delay=0.14, delays=0.05/0.01/0/0.09, dsn=2.0.
0, status=sent (delivered to command: /usr/lib/mailman/mail/mailman post abc) Sep 25 22:37:21 personal2 postfix/qmgr[3822]: 03AE7177B: removed

Nothing shows up in any of the log/mailman logs. All of the qrunners etc. are running.

Any help would be appreciated.
