However, the content-type is already specified, so it shouldn't need to rewrite. However, I notice that your original message is missing a MIME-Version: 1.0 header. My guess is that vger's logic is that without that header, it can't trust the Content-Type you have provided (and indeed, not including MIME-Version violates the MIME RFCs, I believe). I assumed this was a bug in git-send-email, but looking closer, it doesn't put in any mime information at all! So your sending smtp server is adding in the content-type header, but it's failing to add the MIME-Version header, which I think is a bug (I can dig up the RFC reference if you want). Arguably, git should be generating the full MIME header-set, since it knows what actual encoding the message is in. -Peff - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
