Prevent mail from selecting an MX record

I have a client trying to send mail to a "large" organization that has three MX records.  the lowest MX is a server that rejects my clients email, The receiving organization knows that there is a problem with that particular server but won't remove it from DNS.  Ergo, once or twice a day, we get a rejection when our mail hits that server. Is there anything I can do from my side to prevent our mail server from ever selecting that one MX record to send the mail to?

Sorry, I just can't get them to listen and I need to get mail delivered.

thanx for any suggestions.

my first thought is to block (at the firewall) your firewall from reaching their mail server having the issue.  After a time out it should try the next MX record with the next best priority.

You can also set up a connector for that domain so that all email is delivered to a specific address.  It will then use this information instead of looking up MX records.
Here's a couple examples for different versions of Exchange.

Another option would be to use a hosts file to replace the IP address for that host with the address of another server. Hosts files override the DNS lookup.

Although a specific Send/SMTP connector is probably the most effective, as hosts files are hidden away and get forgotten about.

This worked like a champion.  Outbound queue shows only the two clusters I wanted and not the bad cluster.  Mail is flowing.  
thank you!
