You'd pretty well have POP when you were through. No you would not. And I *strongly* suggest not using POP in this situation. This is a kludge at best. POP loses the envelope, and even if you have the delivery agent save them somewhere - usually headers, since POP provides no other place which consitutes a namespace pollution to start with - there are no standard headers which can be *relied on* to contain them. POP is a mailbox delivery program. It has no business delivering mail to a *site*. Extending POP is an option, extending SMTP is another. Or inventing something new similar to either as you also suggest is yet another, but it is abundantly clear that something else is needed for delivery of mail to sites via occasional dialup connections. POP isn't even in the same league here and was designed for entirely different purposes than delivering mail to multiple users at a site during a single session. The fundamental difference is that mail is considered to be "delivered" once mail is passed off successfully to a local mail delivery agent by sendmail. In addition to the delivery envelope there are a number of other concerns that a pop-based solution does not address, such as DSN.
