My understanding of the new dnsdb txt lookup syntax was flawed.

+Version 4.72
+------------
+
+ 1. TWO SECURITY FIXES: one relating to mail-spools which are globally
+    writable, the other to locking of MBX folders (not mbox).
+
+ 2. MySQL stored procedures are now supported.
+
+ 3. The dkim_domain transport option is now a list, not a single string, and
+    messages will be signed for each element in the list (discarding
+    duplicates).
+
+ 4. The 4.70 release unexpectedly changed the behaviour of dnsdb TXT lookups
+    in the presence of multiple character strings within the RR. Prior to 4.70,
+    only the first string would be returned.  The dnsdb lookup now, by default,
+    preserves the pre-4.70 semantics, but also now takes an extended output
+    separator specification.  The separator can be followed by a semicolon, to
+    concatenate the individual text strings together with no join character,
+    or by a comma and a second separator character, in which case the text
+    strings within a TXT record are joined on that second character.
+    Administrators are reminded that DNS provides no ordering guarantees
+    between multiple records in an RRset.  For example:
+
+      foo.example.  IN TXT "a" "b" "c"
+      foo.example.  IN TXT "d" "e" "f"
+
+      ${lookup dnsdb{>/ txt=foo.example}}   -> "a/d"
+      ${lookup dnsdb{>/; txt=foo.example}}  -> "def/abc"
+      ${lookup dnsdb{>/,+ txt=foo.example}} -> "a+b+c/d+e+f"
