Q1408
Question
If email has been deferred to a member on a local mailing list
(implemented through forward files), and one of our ETRN clients is on
this mailing list, the -R won't flush the mailing list message for
that client.
Answer
That is because -R matches only original recipient addresses, not
those produced as a result of expansion, because these are not (by
default) preserved from delivery to delivery. You can get round this by
setting one_time on the forwarding router, but you are not allowed to
have expansions to pipes or files on routers that have one_time set.
Therefore, you will have to have a separate router for mailing lists
(with one_time set) to the one used for normal forward files that
might specify pipe or file deliveries. However, the problem will still
be present for any user who sets up a .forward file to redirect to any
of the ETRN domains. See the last 3 paragraphs of `../Q1407`_ for a
discussion of an alternative approach.
