Just a small request to all, while we say a big no to catch-all ( they just invite spam and eat your traffic). Dont configure catch-all that are set to "delete". This means you allow mailserver to receive hundreds or thousands of spam each day, process it completely and then delete it. This has been a major cause associated with recent mail1 problems. While this is simply equivalent to no catch-all mailbox as in that case the mails will be denied at smtp session itself and you will save on mail traffic as well. We will now look for such catch-alls and remove them unless you need them to be delivered, as they both conditions are same while the latter helps both you and us.
