That MX has a priority of 100...

[root@mailscanner log]# host -t MX optionsgroup.com
optionsgroup.com mail is handled by 10 smtp.theoptionsgroup.com.
optionsgroup.com mail is handled by 100 mail.uu.net.
optionsgroup.com mail is handled by 5 smtp2.theoptionsgroup.com.

There are two other MXs with a much lower priority. Is there a switch I
need to pull from this?
