the changelog and the examples say that the switch -M can be used to add multiple body lines. This does not work for me, the email always contains only the last line (last -M switch when multiple present)

What platform and also can you list the exact flags you used? I can not reproduce the problem. I assume you used v1.17b+

Thanks.

I used 1.16 becasue the page sais this is the latest stable version. Tried 1.17b11 now which works fine. I am on Windows. Thanks

Added version info in the example page to avoid confusion.
