No, this will not help the OP who should instead focus on getting Exchange fixed. There is no problem with Postfix. A more hands-on postmaster might notice a particular set of domains that are commonly mis-typed (in the same manner) and setup transport_maps to permanently bounce mail addressed to them. Examples of how to do this are available in list archives. -- Sahil Tandon <sa...@tandon.net>
