Colored body without text or images

From a particular sender the email body is colored but not showing text or images. The option “Download pictures or always download pictures from this sender” is not displayed. I use the privacy setting “Block unsafe content except when from whitelist senders”. I did not add the sender ́s email adress to the whitelist. Other email clients display the email properly.

I ́m running eM Client 6.0.23181.0 on a Windows 10 system.

Hi Pascal,
would you mind sending me an .eml file of this problematic email to rust@emclient.com so I can try to find out where the issue might be?

Thank you and best regards,
Olivia
