Full Version: Can I block outbound email to certain IP addresses?

I'm getting lots of bounce messages from Yahoo. It seems that the Yahoo spam detection algorithms don't like all the notifications that my forum sends.

While we could argue about how good or bad the Yahoo anti spam algorithm is, my main concern is to stop any more emails being sent to Yahoo so that I can avoid them blacklisting my mail server.

So, is there a way to block SMTP traffic to certain IP addresses? This way, I could block all emails that are due to be sent to yahoo.
