Shame! Yes, you are absolutely right, this is exactly the point.
Many stuck NDRs magically disapparated to trash!
This brings another little problem: when this router (news_bounce)
is triggered by a normal queue run, exim is perfectly happy. Now
if I force delivery (using the eximon), exim is no longer happy
and barfs via the panic log (3 lines here for legibility):
2000-07-20 14:01:26 13E0z8-00006p-00 failed to expand condition
"${if and {{> {$message_age}{43200}}{eq {$sender_address}{}}} {yes}{no}}"
for news_bounce router: unknown variable name "message_age"
Could it be that this variable is not available for such forced
deliveries? The spec document about this variable doesn't make
me feel that it is only available at some specific moments. Or
maybe the text "at the start of a delivery attempt" refers
to a "normal (unforced) delivery attempt"? If this is the case,
the spec should reflect it, IMHO.
Many thanks Philip for your always valuable help.
