So, how does one set up the acl_check_rcpt section to use the exim_blacklist
that was defined to deny the incoming e-mail from the named domain?

I went back and looked again and found the following:

acl_smtp_mail = acl_check_mail
acl_smtp_rcpt = acl_check_rcpt
acl_smtp_data = acl_check_data
acl_smtp_mime = acl_check_mime

Just curious, why bother having scl_smtp_xxxx when they become acl_check_xxxx?
Why not just use acl_smtp_rcpt? Just goes to show what little I know about
exim. I don't do anything fancy with my setup, because it is just me on my
home server.
