Viewing QR codes inside email
Try not to block downloading and showing photos and QR codes inside emails. Some of them are useful! Or, leave it to the user to enable showing them when opening an email, like Outlook does.
I have tried all the settings in your system, but could not make it work.
I might remove this account from here and stick to the Gmail one. At least that one never disappointed me!
