I have installed Mailman in my RedHat6.2 OS.I sent a subscription to the maillist with a testing email account.

Then I receive a msg like "Listname-- confirmation of subscription -- request 770815".

I reply the msg according to it's confirmation rules.

But I can't get a response msg like "Welcome to the ListName mailing list!"
What 's the matter?Anyone can help me?
