A typical corporate "security" feature, the Chinese text reads "External
Mail". Sadly the same system then sends the message to the header
rather than the envelope recipient. And even sets the envelope sender
to the header "From:" address. You'd expect this sort of thing in an
MUA, but it has no place in server-side email handling software. So
this is another instance of what is sometimes called "crapware".
