I got an xxx@addtodropbox.com address. If any email is sent to that address, Dropbox saves its attachments to the Email Attachments folder in my Dropbox account. It works fine, except in one situation.
In my Fastmail email account, I created a rule that automatically forwards certain emails to that addtodropbox address. I confirmed with Fastmail that the emails are being forwarded. Yet the attachments aren't being saved to my Dropbox account. Dropbox must have blocked the emails or didn't see the attachments.
It works if I manually forward the emails, but not if they're forwarded with the rule. Anyone know why that's happening?
