I'm a hosting provider yes, but I don't greylist my own clients, just greylist
emails sent to their domains.

There's plenty of spam each day that gets delayed by many hours, and by the
time that spam does get through greylisting, the other filters pick them up
and rate them for deletion (so the clients domain never gets them anyway). 

The problem is when a valid email gets delayed for an extended period of time,
that's the thing which has caused me pain.

It seems to be part of life for mail servers on the internet to be broken, not
setup correctly, not follow RFC's, etc, which is why we manually whitelist,
but from the clients point of view they just want their email to work and not
be delayed (and they don't care about the fact that the sending mail server is
broken), so such delays that cause them pain, cause me pain. This is why I've
had to stop greylisting for some domains to keep the client happy.

Ideally, I wish I could find an automated solution to have greylisting on
while still not delaying valid emails, and having no administrative overhead.

Regards,

Michael.
