Openssl makes it easier to create my own CA and issue certificates for local 
boxes with specified uses such as WWW and EMAIL, but I am not clear on the best 
approaches for multiple domains and boxes. I have dedicated individual boxes 
to use as web server, email gateway, and email server, and multiple boxes for 
each job to enable online backup and offline upgrades. Should individual 
certificates be created for individual boxes or should the same certificate be 
shared between all boxes allocated for each individual job?
Thanks for any information.
