When I look at the list of e-mails in my inbox, the first line for each mail shows the subject, while the second line shows the sender - mostly.
For some e-mails, the second line shows “To:” and then my e-mail address. In these cases, the profile picture for these mails also changes to my own picture.
This consistently happens for at least one person regularly sending me e-mails.
I have tried all kinds of settings, but this behavior never changes. I can even see similar behavior in the screenshots in the K9 documentation here:
How do I make K-9 always show the sender?
Thanks in advance for any help!
