If I deny an IP address from connecting, then I don't need to deny it from
relaying also, correct? Correct. It will not be able to make a connection to
relay the message.
And if I do allow an IP address to connect, but deny it from relaying, then
that IP address can only send mail to domains for which my Exchange org is
responsible for, correct? Correct, but be aware that if you limit your
exchange server to certain IPs, only those IPs can connect and the rest of
the servers on internet will have problems. This may not be a problem is all
mail comes in from a single server such as a spam/AV filter.
