Here I disagree.
Tonny describes again a use case that we've listed already last year.
See sample 2-2 on http://www.martin-stecher.de/opes/smtpusecases.html
No doubt that it is a very important one.
This and other examples of group 2 are the "useful identity-based services"
you are referring to, aren't they?
And these are all request satisfaction examples, not response modification.
Again: Response modification is only useful if the callout service makes
use of the original response data, which in SMTP is the SMTP reply.
The only service I can think of, that does this, is a logging service.
Is that one strong enough to have response modification in the SMTP
deployment?
Or can you please describe another important service that makes use of
the response and modifies it?
When the response comes back indicating that there's a problem with
the recipient name, the OPES processor sends that to the callout
server, and at that time, the callout server can pick an alternative
method for finding the recipient. This seems obvious to me ...
I'm not sure why it seems obscure to others. I wrote a white paper
for Novell several years ago about "global identities" that used this
method for resolving delivery addresses.
