No mention of RBLs or greylisting ...
Quite.
When my ISP switched on greylisting my mail immediately went from a
spam:ham ratio of 80:20 to one of 20:80
But the variable delay, which is not under your control?
You're right: its not.
My users complained loudly about that minority of mails which took an
hour to arrive. I had to turn it off.
I know what can happen, and also that those complaints can arise from a
total misunderstanding of what e-mail is designed to do: that it is
*not* an instant messaging medium but it is a reliable one despite
delivering over sometimes flaky networks. IOW demanding instant e-mail
delivery is quite unreasonable.

And if your business is predicated on instant e-mail you are setting
yourself up for pain.
If it needs to be *instant*, have them visit a web page to enter service
requests.
