By default a query-style ${lookup ...} expansion returns all matching records
separated by *newlines*, not the colons you need. And since you have to
extract all records and match against each in turn you could simply put all
patterns in a text file, one pattern per line, and refer to it by filename,
like so:

hostlist domain_reject = /etc/exim/domain_reject
