Version 2 of the Exchange 200x Catchall Script Released
Most Unix and other traditional mail servers can implement a single mailbox that receives all mail that does not belong to any mailbox. These days, in terms of security and usability, this is not really recommended in most cases. If you still need to implement this, Michael B. Smith just released a new version of a script that performs this for Exchange. Added is that ability to "catch" mail for more than one domain.
