Yep, thats what they want.

It should not send a size reply, because only the one transport wich
sends it on (one of multiple) has got a size limit, the other transports
and the local deliverys shall be able to get big mails.
So I think this behavior

As Exim (as it seems) gets all Mails, it should know about them all.
Also it doesn't but anything in the rejectlog, but only in the mainlog (as
