This document refers to Schleuder version 3.4 To read about older versions of Schleuder please see the older docs.
User-relevant changes in version 3.4 compared to version 3.3:
- HTML is stripped from multipart/alternative messages if they contain keywords. This is to prevent those keywords from being visible to recipients of resend-messages, and thus leaking confidential information. Filtering the keywords from the HTML is not solidly feasible, so removing the HTML-part entirely is the only option. Generally we recommend to not use HTML with Email at all, as it brings a lot of problems and insecurities.
