I perfectly understand what SMTP is, and I perfectly *don't* understand why having a 30 minutes delay or even a 2 or 3 hours delay in some conditions is tolerable. > > SRS changes the MAIL FROM for one user every 3 or 4 hours. so > > every 3 or 4 hours he comes stuck in greylisting server again and > > again.

I don't know any better solution in order to be SPF compliant when you have a redirection service. please tell me, I'll use it. but any method will require : * sender rewriting * time dependant hash in order to avoid open relay and will create such a problem.
