Hello, We recently installed a new mail server, now using Postfix rather than Sendmail. Since the installation, local subscribers no longer are receiving the newsletter. Specifics - SuSE Linux 8.1 base system Postfix 2.0.7 Listserv 1.8e @computeruser.com subscribers not receiving newsletter. The listserv.log shows the local subscribers being sent but the Postfix mail log shows no record of them except for one user that bounces because she is no longer an employee. My Hotmail account does receive the newsletter. Otherwise Postfix is working properly. Other messages from Listserv are being delivered locally (subscrition notices, daily error monitoring reports, etc.) Output of postconf -n is below. Are there any special settings about Listserv and Postfix? Or is there something else I should be looking at?
