This is exactly right.

So the question is: why isn't the domain itself sufficient to differentiate the two 
accounts? 

It sounds as though on the SMTP end, it is: mail comes in for [EMAIL PROTECTED] and 
[EMAIL PROTECTED], and the SMTP server knows enough to store the mail separately 
based on the different domains. 

But the POP3 server doesn't have access to that information? [EMAIL PROTECTED] logs in 
to get his email, and the POP3 server doesn't have any way of knowing whether is fred 
from firstdom.com or fred from seconddom.com?
