According to the Groupwise driver doc Internet Email Address is:

This attribute is generated by GroupWise on a Create or Rename event, or when any attributes used to generate Internet Email Address are modified. The shim queries GroupWise for this value and writes it via the Publisher channel to eDirectory.

The question I have is, is there a way via policy to query this value?
It doesn't appear to have a mapping to a value (I'm assuming it isn't actually stored, rather derived)

I'd like to be able to grab it an populate the value on a sync event to get everything trued up.

Thanks in advance!
