[Mailman-Users] Mailman can't send mail

[Can Cizer]

 Hello,

 Although i can create a mail list and i can send mail to the list,that mail
cannot be sent to other members of the list ( even no subscribe mails ). The
mails that sent can be seen by the admin on the mail list page (tend to
pending moderator requests). What should i do to fix this problem? ( I saw
same topics in the archive,but they could not help me. )

Information about system;

- The version of the mailman 2.1.9
- It is installed from source code.
- The server - CentOS 5
- The mta - qmail


thank you for your help
