Hello, I'm running mailman in the following server:

Mailman 2.1 Linux RedHat 7.3 qmail Installed by RPM

My list is called "news", and the domain is "programacambio.org" When i try to subsrcibe by email, sending a message to news-request@programacambio.org with this subject "subscribe", i have no response, and my account isn't added. When i send other commands, like "help", "who", etc., all works fine. I saw in logs (specifically "subscribe"), and all times i try to subscribe by email appears as "pending". What's the problem ? Thank you...
