Hi, I think this is due to the way the links are rendered in general.
To achieve your goal you would need to use the following: mailto:debian.a...@manchmal.in-ulm.de[Christoph Biedl] instead of: Christoph Biedl <debian.a...@manchmal.in-ulm.de> See: https://asciidoctor.org/docs/asciidoc-syntax-quick-reference/#links Is that acceptable? Thanks Joseph
