This looks suspiciously like Postfix is adding the second
X-Original-To ([EMAIL PROTECTED]), perhaps because it appended
'.obstruction.com' to the address for delivery (noted in
Delivered-To).

I don't think there's anything that will break on your end. As far as
other users go, who knows? I don't recall seeing list mail about this
issue before, so I suspect that using the first field works for those
using RECIPIENT_HEADER. Hopefully, in most cases, it's the only
field.
The only way I know to find out is to put it into CVS and see who
hollers. I'll let Jason make the call on that.
