Since you are prepared to scan your file linearly (I assume, therefore,
that it is not very big), you can just make it into an interpolated file
rather than a lookup:
host_reject_recipients = "+allow_unknown:/etc/exim/host_reject_recipients"
However, if you do that, you can't have anything other than host items
in the file, so your comments will have to go. The obvious way round
this is to have two files - one that you edit with comments, and another
that has the comments stripped. Use a script for updating that
automatically rebuilds the stripped one.
