To everybody that responded, thank you. I found that ZEND link to be very
interesting. Based on what I've read here, and based on a couple quick
tests telnetting into a couple mail servers, I've found that most are not
set up to do a VRFY and most say that every email box does indeed exist for
its domain. Thanks again.
