The only issue I can think of is that is an attacker gains access to your server, then both your DNS and mail belongs to them, rather that having only one compromised. Of course, if they were on separate machines, then it is likely that if one was compromised, then the attacker could go from one to the other without to much difficulty. Still, it is an extra layer of security.

Neither are historically secure, but H.I.M. is right; stay on top of the vulns discovered. It doesn't matter if they're on the same partition, physical disk, or in the same case. Good luck to ya.
