It will also help me if you can write e-mail clients without this feature, so I don't need to try them myself
People keep sending me e-mails with pictures embedded in the text. While this is nice in principle, the problem is that those pictures have some mbyte in size each and together they eat up my cellular data volume.
Unfortunally, you can't tell iOS Mail not to load e-mails above a certain size (or to download those pictures automatically). You can switch off downloading images from remote servers (I did that), but that doesn't work for pictures embedded into the e-mail. Also, attachments of a certain size are not automatically downloaded, but somehow pictures are not considered to be attachments.
MacOS Mail has the possibility to set a limit for POP accounts, above which a confimation is needed before download. Why on earth not on iOS.
I also tried spark as an e-mail client, but I don't find that option either. And I don't find it in the description of any e-mail app.
Is there an alternative e-mail client to support this feature?
