How many recipients does the message in question have? The cutthrough delivery works only if all the recipients have the same destination.
I think in all cases there is a single recipient, but at the least they are all destined for the same domain on the same remote host. Here's an (anonymized) example transaction:

Can you tcpdump your connection to check if there is at least the cutthrough attempt?
Let me give it a try... Danke. -- Rob Szarka http://szarka.org/ -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
