Hello,
Okay, it's Friday afternoon, and the 13th!, so this could be a dumb
question :-)
I need to try and send messages sent to one domain, and received on an
exim mailhub, back out to another domain without changing any of the
header or envelope addresses *and* using MX lookups for the new domain.
Can it be done?
I need the MX lookup bit since the new domain has several mailhubs and
the DNS will specify the preference they are to be used in. I have no
control of the DNS entries for the new domain.
As far as I can tell I can send mail out to another host without
changing any addresses by using the manualroute router, but this doesn't
do MX lookups. So I would have to manually keep changing the route list
whenever something happened on the receiving mailhubs.
Alternatively is to use a dnslookup router to the new domain, which
gives me the MX lookups, but then I have to specify the routing domain
(using 'self=reroute:xxx') and that changes the envelope address. (I
have to specify routing because a dnslookup of the initial '$domain'
simply returns the MX records for the local host; so I need to specify
where to send the message on and that causes the envelope address to
change it seems).
The closest I have got so far is to use a manualroute router with a
dnsdb lookup of the MX records in a route_list. Unfortunately though
this returns the MX records but with no regard to the MX preference
value. I can see no way of 'sorting' these without getting more
complicated and running some external program to sort them!
A route_data option to sort the MX records according to the preference
value would be nice :-) I think that would then solve this.
Hope it makes sense! Thanks,
John.
