Yes. No.
You've identified the cause, but reversing the order of the items isn't
the correct fix. You basically just want to test if two strings are
equal (ignoring case), with none of the domainlist matching logic of
handling named lists, regexps, files or other list items.
condition = ${if eqi{$sender_address_domain}{$dkim_cur_signer}}
