Preface: - Firsty: yes, I'm fully aware of all issues associated with https://en.wikipedia.org/wiki/Callout_verification (and there is a LOT of them!)
Which is why SA does not support such so-called verification in any way. It never will as long as I'm a contributor.
- I'm not looking for debate about general usefulness of Callout verification (and the system for which it is being investigated is not general-purpose e-mail system).
This is a bit like saying you don't want to debate the general usefulness of spamming. And then going on to ask about ways to spam. I do not care about why you are trying to use SMTP callback verification, because it is a fundamentally broken concept. If it looks like a solution to you, you are refusing to look at solving your real problem.
All set then. SA is not the right tool for you. Try something like Exim, MailMunge, or MIMEDefang that let you write arbitrary code for the mail-handling flow. I suppose you may be able do it in sendmail.cf too, if you're into self-torture.
