Hello Wolfgang, thank you for your explanations! One more question: it would be nice if the rule under the back-address would have the same length an the back-addres. Is there a convenient way? I tried something with \textbackgrounds (example below) but without success. % from the wiki: \startuseMPgraphic{underline} \iftracepositions show_multi_pars \else draw_multi_pars \fi ; path p ; p := boundingbox currentpicture ; currentpicture := currentpicture shifted (0,-StrutDepth/3) ; setbounds currentpicture to p ; \stopuseMPgraphic \definetextbackground [underline] [location=text,alternative=1,background=underline,frame=off] \setupletterstyle [backaddress] [alternative=yes, before={\starttextbackground[underline]}, after=\stoptextbackground] Andreas
