Option to opt out scanning of all folders

Feature Proposal
1

Expected behavior

I’d like to see an option to opt out the scanning of all IMAP folders.

Actual behavior

Right now, every IMAP folder is scanned from time to time.
For me that’s really messy because I automatically store emails
from newsletters and some mailing lists outside of =INBOX but
they still appear in Delta.Chat

I also would like this feature. Because I use a extensions address an a server sided filter to move all mails adressed to this extentions address into the DeltaChat-folder.

Maybe the “spam folder” should always scanned to never miss a message.

for casual readers: do not worry: just use Delta Chat as any other messenger, the onboarding is one of the simplest one out there: just enter your name

so, the above and the following is about what is happening under the hood, for advanced user only

Delta Chat of today is no longer about shared usage but uses IMAP/SMTP as a relay only.

therefore, it also does no longer scan folders, but only listens to the INBOX.
