[Mailman-Users] no response while posting a message

[Victor]

Hello,

I installed mailman successfully. I created a mailing list named mailman. Then I subscribed to this list and I received the confirmed and welcome email. However, when I posted a message to this mailing list, nothing happened. Nothing wrong appeared in the mailman log files.

The urlhost is cs.heilongjiang.edu and the mailhost is cs.heilongjiang.edu. The mailing list address ismailman at cs.heilongjiang.edu. I think the problem results from the mailing list address. Could you please give me some advice?

Thank you very much!
