I want to deny incoming mail from domain blu0.hotmail.com.

I have put in /etc/postfix/sender_access the following line:
blu0.hotmail.com 554 Spam is not welcome

and then I run
postmap /etc/postfix/sender_access

and
postfix reload

Is that enough?

Sorry I sent the same post twice.

Not unless "postconf -n |grep sender_access" turns up something.

In any case, I'm not sure that refusing to talk to a single hotmail
server will accomplish anything useful.

What are you trying to do?

what do you mean by "from"?
- the domain of the client machine? (reverse dns)
- the domain of the envelope sender address?
- the domain of the from/reply-to header addresses?

do you really get mail sent by <joe(a)blu0.hotmail.com> ?

you may want to show a concrete example of what you want to block.
