esp32-cam take a photo and send by email, problem with ipad mail app

[Jay-esp]

I send a one line message and a picture, it works, in gmail (web) i can open the mail and the message and picture are shown, however in the standard ipad email app it does not show the image and i only get a placeholder "click for download" " mimi-attachment" but nothing happens when i click.
I searched the net and it might be caused by content-type NOT being multipart/mixed...
Any clue how to solve this?
The email content:

Date: Wed, 19 Jun 2024 00:18:16 +0100
Mime-Version: 1.0
Content-Type: multipart/alternative; boundary="=_TX=JH=vvOD6J";

--=_TX=JH=vvOD6J
Content-Type: multipart/related; boundary="=__EjBfF2D5k3A";

--=__EjBfF2D5k3A
Content-Type: text/plain; charset="UTF-8";
Content-transfer-encoding: 7bit

Post in de brievenbus.

I delete my previous reply because it's not relevant.

I discovered that you are sending inline (image) attachment with message.addInlineImage which may not support by some client included Apple mail app.

You should attach image as normal attachment with message.addAttachment.
