Since Odoo 18, emails coming in to an alias creating account moves (vendor bills) get rejected if they do not contain an attachment that can be read by the system. This means that sending a plain email receipt with no attachment bounces, when it would be nice to have a vendor bill with the message in the chatter as a minimum. This module checks for attachments and injects one, in the form of a simple pdf containing the email header and contents, if there was no attachment to begin with. This should enable sending of a simple email and not having it bounce due to there being no attachment.
