Hi Don,
Yes it looks like for MXD AADC std letters auto/mach should route to Pittsburg 150 instead of Buffalo 140. This is strange for the presort modules used in MP4 are from the post office. I can't even find Buffalo 140 in the presort Lmodule used for this sort (L011). Would it be possible to send your file along with your mailing specs to
tech@melissadata.com? We can then replicate the problem and report it to our QA and programming department for a fix.
NOTE: This may be correct if you are adding an SCF destination with your mail but we can confirm this if we can get the file.
Paul
