Hi Mike,
It is actually part of a large ACL. The first part checks if a domain is listed in a particular file which contains a list of routes. The second part verifies that the listed address is one that we have defined to accept in the second file.
I have a couple of files that are used for different reasons (staticroutes etc) and this is one of them. In this case it is to allow us to spam filter messages to be forwarded on to Exchange 2013 or Office 365. The latest versions of Exchange do recipient validation after the data part thus screwing up the call forward that we use for earlier versions.
All the best,
Colin Waring.

I'm curious why this is necessary…

As Colin mentioned, in the Specification the description of the *$domain* variable (p. 127 in the PDF from Exim 4.85) says:
When an address is being routed, or delivered on its own, this variable contains the domain. Uppercase letters in the domain are converted into lower case for $domain.
So surely there shouldn't be a need to translate it to lower case using ${lc:$domain} ?
Or is the documentation wrong and the domain name not converted to lower case before being put into the $domain variable?
Cheers,
Mike B-)
