If I look at the source code of the email it looks like this:
Subject: Re: Aw: Re: Re:
There was a non breaking space entered. The first one seems to come from an Android app:
Diese Nachricht wurde von meinem Android Mobiltelefon mit WEB.DE Mail gesendet.
The second one must have come from the Jolla mail client. Interesting that Web.de rejects its own subject lines… Or does the Mail client change the non breaking space to a different one? There a plenty of different none braking spaces on unicode.
