Is there a more detailed explanation of that problem?
Philip often states that Exim's delivery model was designed for an
always-connected situation where most of the mail is deliverable on
the first attempt. There was certainly no concept of business-as-usual
deliberate deferral (of which greylisting is an example) around then.
It's not trivial to tune Exim's retry mechanism to optimize delivery
under greylisting I guess.
