I think there is a malfunction. The malfunction is that sometimes I can not switch the delivery format to, e.g., HTML. There's just no menu element "Options > Delivery Format".
For example there's a draft mail I created on my iPhone earlier which includes images.
When I edit this draft mail using Thunderbird, Thunderbird is in this strange mode and thus I can not switch delivery format nor add rich text formatting. The images are represented as attachments. That's very bad.
Now, when I add an element of rich text on my iPhone to this draft and edit this draft in Thunderbird, Thunderbird switches to "delivery format = auto detect" and shows rich text formatting controls. Additionally, the images are now inline with the text and I can move them around or rearrange them.
Speaking of iPhone, I don't know why this issue is so complex with Thunderbird. In Apple Mail there's a simple button available in the composition window to toggle between plain text and rich text editing. That's all. Just works.
