I am running ISPConfig 3 on Debian Wheezy. And I used the perfect server setup guide. I have created a new mailing list "Newsletter". I wanted to let users confirm their email address before being part of the mailing list. Clicking on the link works, but replying to the email or sending a new mail to newsletter-requestatmyserver didn't work as I have a catchall account and the mail is just routed to my mailbox. So I set the setting to approve only. But sending a mail to newsletter@myserver redirects it back to my inbox. How do I post to the mailing list? What settings can I adjust for mailman to see the mails?
