Thanks for answer. It seems GPGrelay is not longer maintained by its developers but is still working with a charme if gpg.exe 1.4x is used. So, how to work around and supply keys to GPGrelay even if using gpg version 2 and up? Regards, Chris http://sites.inka.de/tesla/gpgrelay.html http://is.gd/c4duwS (Sourceforge)
