I have improved the readability of your snippet by using a macro and more
space.

The problem here is that $sender_address_domain is not added to each entry
in the file. If you have a file containing blacklist.com on a line by
itself then the result of expansion will be blacklits.com:/sender.com
which is a syntax error.

Note that the EOL string in ${readfile can be more than a single
character, so you should try

dnslists = ${readfile {USERPREFS/rhs-blacklist} {/$sender_address_domain:} }
