I understand that you want to blacklist based on the *source* domain.
But the "domains = …" condition checks for the *destination* domain.


    driver = redirect
    condition = ${lookup{$sender_domain}lsearch{/etc/eximblacklist}}
    data = fail: …



But I'd use an ACL instead of a router:

    …
    acl_smtp_rcpt = acl_check_rcpt
    …


    begin acl


    acl_check_rcpt:


        …
        accept  domains = +local_domains
                local_parts = postmaster : abuse


        …
        deny    sender_domains = +exim_blacklist
                message = sorry




    Best regards from Dresden/Germany
    Viele Grüße aus Dresden
