We have a Linux RH9 Box running Plesk control Panel. 2 days ago, our Mailman mailing list installation became corrupted, and is no longer sending posts to our members. Posts to our lists, reach the list archives, but do not get forwarded out. We need someone to look into this and repair the problem. It was most likely caused by a recent update installed via the updater in the plesk control panel, but we are not sure.
