For the posterity of the list, and the wonderful information that's been
provided so far for all of the newbie nincompoops out in CentOS list
lurker-land ... Let's say that I'm a nincompoop newbie sysadmin from
HostCo that would like to avoid breaking any rules. (In reality, I'm a
PHB, and I let my sysadmin worry about the rule-breaking.) How would I go
about providing a good, solid *matching* ptr (as in, mail from
AcmeWidget.com reflects to mail.AcmeWidget.com at x.x.x.219 ... which also
happens to be mail.hostco.com) for the bazillion and one virtual-hosted
email accounts on mail.hostco.com?
