It sounds like you get it now, but you make too many assumptions of the servers. Server A doesn't know what Server B expects and understands, nor does it care. Server A *has* to pass on the original address if it's relaying the mail. Server A knows whether it's relaying or doing local-delivery, but it's still a bit messy, which is the real point here. LuKreme: sure, it's easy to describe the generally-expected behaviour, but I suspect Wietse's point is that you're welcome to write the patch and make sure nothing breaks. *grin*
