So far I have heard of none. Please explain why do you think that such a proof cannot have bugs? (How exactly do you formalize all the requirements? That formalization phase is not bug-free).

OTOH qmail has a great track record. Posfix is not so bad either.

Plus the fact that a "proof of correctness" is a mathematical proof that something is "logically true".

The trouble is that science, the study of the real world, has no concept of a proof of correctness - all it knows is proofs of incorrectness, and by implication "well, it's probably correct because we haven't proved it false".

A proof of correctness, BY DEFINITION, must instantly be worthless immediately you try to apply it to a real-world, or scientific, problem.

Cheers,
