Precisely - in fact, it increases the work the receiver has to do, probably substantially.


+1.

When discussing different protocol models, folks should be required to explain a collection of relatively obvious cost/benefit differences, such as:

1. Latency/Delay

2. Transaction (Round-trip) exchange count

3. Robustness/fragility

4. Administration

5. Privacy

6. Authenticity/Spoofing

...


For the SMTP push model (and ignoring the possible pull last-hop):

1. Low latency
2. A bit too chatty, but pipelining largely fixed this
3. History demonstrates high robustness
4. Low administration (only DNS MX)
5. Privacy is theoretically non-existent
6. Authenticity is demonstrably horrible
