Basically rarcoa.com is configured to tell mail senders to fail to (re)send emails, they can only be sent from raroa.com. Anyway, I think this is supposed to be fixed in mailing list servers, they need to strip these headers and insert their own rather than leaving them intact only later to get rejected due to honoring the header's stated policy. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
