Qmail lets you implement this using virtualdomains. You can
virtualize a domain on a per-use basis. So tell the qmail running at
location A that [EMAIL PROTECTED] is actually [EMAIL PROTECTED]
Unfortunately, both sites A and B have to be running qmail and must be
configured with the user table. There's no global way to do what you
want. I suggest that you colocate the central mail server somewhere
where there's plenty of bandwidth, and configure it with the user table.
