OpenSSH disable ControlMaster for given hostname

I am using OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 with Mac OS X Snow Leopard. I have ControlMaster feature configured to maintain persistent connections. My ~/.ssh/config have the following:

Host *
  ControlPath /ms/%r@%h:%p
  ControlMaster auto
  ControlPersist 4h

Host *.unfuddle.com
  ControlMaster no

However, from what I see - even when I am trying to use SSH for unfuddle.com hosts, master connection get always created:

Thanks,

Your * host stanza is catching it. Put more specific host stanzas earlier.

As described in the answer to my similar question on SuperUser, you can use the "bang" syntax to exclude specific hosts from the original Host * stanza, like this:

Host * !*.unfuddle.com
    ControlPath /ms/%r@%h:%p
    ControlMaster auto
    ControlPersist 4h

In my situation, I found that the order of the Host sections when using a Host * seemed to be irrelevant, but the above method always works.
