But I presume that it must therefore require the parent process to reap
the child?

What that means is that Exim tried to wait for a remote delivery
process, but the process had gone away. This is certainly related to
SA_NOCLDWAIT in systems that support it.

The code in deliver.c that is conditional on SA_NOCLDWAIT doesn't in
fact use that option; it is trying to ensure that it is NOT set.
Therefore, you could try using it anyway, in case there's some other
option that needs to be unset.

Otherwise, you'll need to discover how to make your operating system
keep completed child processes around so that the parent can wait() for
them.
