I recommend:

        Connect:linkedin.com    ERROR:5.7.1:"550 Mail refused"
        From:linkedin.com       ERROR:5.7.1:"550 Mail refused"

Salt to taste for your environment/MTA, but since the spammers running
LinkedIn seem very unlikely to stop, this appears to be the optimal
way to conserve bandwidth and time.
