When generating a mailing list from Export we should be able to exclude inactive addresses from showing up in the file.
Address processing does allow us to set precedence of a active address so an active address will export if it exists. If all addresses are inactive it will export an inactive preferred address.
There should be a window to select this option like there is for phones.
The "Has No Valid Address" could possibly make it easier to exclude constituents from the export altogether but this is often not what is needed.
