Backup photos to email provider automatically

Will be great to see this option:
I have unlimited email box, so it will be very useful backup all my photos inside of it automatically (choose an folder from phone and all goes in email server, in e2ee crypto files).
Profit:

  1. unlimited size of email (we are not talking about speed, it can de slow it doesn’t matter)
  2. all photos will be encrypted as e2ee (dream for me and night mare for provide)
  3. with Deltachat it is very simple, easier. It just works
  4. popularity of DC will grow

I think this is a side functionality for Delta Chat. There are a lot of more useful proposals for improving DC.
