10 ) Use one of the various sanity checking sites to validate some 
subset of your hosted domain configurations.

We used to like http://www.dnsstuff.com a lot, but they've gone 
commercial. It's still a great service and possibly worth the money (I 
bought a membership but will be comparing it with the other free 
offerings in the coming months before our renewal is up to see if 
there's really enough value add).

Free sites that perform similar DNS configuration checks that I know of 
are:

http://dnssy.com
http://www.intodns.com
