This is getting somewhat off-topic, but Mailman warns you during the sign-up process that this password will be sent in cleartext, so do not use a valuable password. In fact, if you leave the password field blank mailman will kindly generate a random password and send you that. If your subscription status on a mailing list is valuable enough to care about compromise, then I recommend you not use an email list at all.
