Love Postie - it's so powerful.
I have tried sucessfully to use Postie to email posts into a custom post type (Document). However, when I add categories defined against that post type to the subject like below, the categories get ignored.
The categories in question are in their own category list under that plugin's menu and they appear to be normal categories in that they live in the wp_terms tabel.
Is this a bug or can I make a feature request to integrate custom post categories into Postie please?
