The problem is the Message-ID parameter. It's not legal to have ':' before '='. I added a workaround to v1.2+, but v1.1's code is different and I'd rather not change it much anymore.

Thanks, I had already figured out that it somehow depended on the headers and that helped a lot! :)

For the archive: another problem was, that the Message-ID was not unique...and putting it between "Content-Type" and "boundary" does not seem to be a good idea at all...

Thanks,
