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
