Rated 5 out of 5 stars

I wanted to see 'X-Delivered-to' information in a column.
I clicked > Options > Custom Column Editor > General
Added the following ...

ID: test
Mail Header: X-Delivered-to
Column Name: Delivered To
Tooltip: Sort By Delivered To

Works fine, could not find any examples on the dev's website, so hope the above helps someone

This review is for a previous version of the add-on (6.0.4).
