Hypothetical Scenario:
Some spammer start sending me emails while I am away from my phone(or I am distracted), do DC download all messages??? (downloading messages have a cost to me)
If the answer is “yes”, I think that messages from unapproved contacts should not be downloaded by DC(only download the headers), and an option(button?) to see the full message, should be provided.
Delta Chat version
0.92
Expected behavior
Unwanted messages are not fully downloaded, just the headers are downloaded.
Actual behavior
Messages from unaccepted chats are fully downloaded, I guess.
Yes, it in contact requests - I called it SPAM folder
I think if one would implement the feature we talked in another thread (download unseen messages only) then that option may put restriction on contact requests too.
Actually it’s easier for this case, since it isn’t encrypted message, so DC may pull only headers from the IMAP and to display a message one need explicitly click on received subject to pull the whole message from IMAP server. So if “download unseen messages only” option activated it can affect workflow how DC pulling unencrypted messages, or it might be a dedicated option in settings that enforce to download only headers for unecrypted messages.
Yeah, and options like “Do not download media” that allow me to decide if I want to download a big message or just ignore it, for example showing me in a image message a button [DOWNLOAD IMAGE (2MB)] so I can view the size and decide whether to download the attachments or not.

I think the spec(s) for the approach of this issue (and other basic ones too) should be collected somewhere in the wiki to show them clearly for everyone. This would prevent many repeated questions of users and makes development discussions easier and even FAQ could target to that.
Here is the editable (wiki) entry. It includes a description of the current default usage mode, and is exactly there to collect the problems and corresponding solutions.
