Isolate the ACL into a config file as much as possible, that is, create
the smallest config possible, that still fits your need:


    acl_smtp_recipient = accept
    acl_smtp_mime = acl_check_mime


    begin acl


    acl_check_mime:
        deny condition     = ${if eq {$mime_content_type}{message/partial}{yes}{no}}
             message       = MIME error: MIME type message/partial not allowed here


        accept



And now test this with a handcraftes message stored in message.eml:


    swaks --body ./message.eml -f x@??? -t x@??? \
        --pipe 'exim -C exim.conf-test -bh 192.168.1.1'
