What Stefan is asking for falls, IMNSHO, in the category best addressed with *external* diagnostics, already well served. - first, as PH has stated in another way, it covers an issue that is seldom problematic. - secondly, looking at what retry rule(s) activate is viewing the symptom, not the cause. There is usually a causal pattern - flakey far-end, flawed local router, broken local user entry, or such - that gives rise to a need for a retry. Exim can already log Queue time and Delivery time. A grep/exigrep or eximstat will show that a retry is not a common event on well-configured servers. The majority of traffic succeeds on first attempt. One may easily select the few overly long queue times to see if retry has been involved. Most such will show problematic destinations or other common cause, often a blindingly obvious one. One may examine the source, destination, protocols, and message format & content in more detail to see if whatever caused the delay / retry is correctable on the Exim server. Once local config errors and far-end problems are removed, fewer than one message in several thousand should remain 'mysterious' as to retry. For modern SME business use, where a critical communication needs to be followed up 'same day' or 'same hour' by fax or phone, not next Tuesday, we have configured servers to 'final fail' on retry in as little as 13 minutes, not 3 or 4 days. It is still an exceedingly rare event.
