I removed "relay_transport" and inserted "transport_maps = hash:/etc/postfic/transport" containing ".our.local.domain relay:[MDA server IP]"
I sent a message from another server and got the attached info in the logs:

My apologies.
I am not permitted to post *actual unobfuscated* details to a publicly
accessable mailing list.
The *actual unobfuscated* recipient address domain is "our.local.domain".
It was rejected because the system tried to deliver it locally to the relay
rather than pushing it to the MDA.
I can try replacing "relay_transport" with "transport_maps" to see what
happens

The "relay_transport" parametr is not table-valued. Its syntax
is "transport:nexthop", not "type:table".

This goes into one of the tables named via "transport_maps", not
"relay_transport".

Logs that show the *actual unobfuscated* recipient domain that got
rejected, and the result of "postmap -q" for the purported lookup
key in the transport_maps table in question. Post the output of:
$ postmap -q .our.local.domain $(postmap -xh transport_maps)
with ".our.local.domain" replaced by the actual unobfuscated domain.
