Hi Alex,
Apparently MR currently allows doc but not docx as an attachment format. This is confusing for calibre users, see for example:
https://www.mobileread.com/forums/sh...d.php?t=282713
For calibre users, it would be useful to allow the follwoing extra filetypes:
*.docx
*.py
*.recipe (these are just python files used by the calibre news download system)
Thanks
