I have installed Rhat 7.2 and Mailman 2.0.6 and all is working except for the mail processing. I get the messages and approve them, but they are never sent. The following error is logged in the smtp log:
All reipients refused: (111, Connection refused)
Sendmail is able to send and receive mail. Is there something I need to have opened specifically for Mailman? Any help would be greatly appreciated.
