Uh, I don't remember at all. Seems I did that in 2011, still have those sourcer. However I don't have that "header" file any more. It seems that this 'hopdelta' parses an e-mail header, right? So I think you can just take any e-mail, for example this one, extract the first few lines, and keep it in a file. Will that work? ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
