We installed a the lastest version of Majordomo. A month or two later, it just stopped sending the approval email and welcome message to new subscribers.
When the list-owner fills out a form (web interface), it submits a mail request to approve a new subscriber. It used to send a mail notifying the list-owner that the new subscriber was added as well as sending the new subscriber an email welcoming them to the list. Now it just adds the new subscriber and doesn't send out any mail.
Is this a sendmail or majordomo issue? Any ideas where to look for an answer?
