I got this message in the maillog file. HTML: May 11 12:00:01 server1 sendmail[5824]: STARTTLS=client, relay=[127.0.0.1], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 May 11 12:00:01 server1 postfix/smtpd[5821]: BB2A141E051: client=localhost.local Dose this have to do with the certificate we made during server setup?

It seems the certificate you created during the setup doesn't match your hostname. But you can ignore this.
