The lessons of this example are two-fold:

   1. CBV significantly contributes to the load of SMTP connections
      because the CBV itself initiates all sorts of verifications (like
      SPF, CSV, DNS domain verify, DNS BL's, static IP BL's, CBV itself
      in a loopback scenario etc.) and as such decreases the reliability
      of mail delivery.

hmm, a good generalized statement, but CBV runs on its own. You can't
control what others will have.

Right.  And after having made this realization, you then promptly forget it:

1) Considering the fact you were having bandwidth issues with your RBL
setup, this is a clear corrective manner on your end.  For example,
decreasing your own socket timeouts for your RBL lookups.

Now you're trying to tell Rolf what he has to do to make your mail server
