I've just tried to upgrade from my somewhat pre-historic 0.52 to the new
wizzo 1.58.
However the rules I was using to do domain re-writing no longer work.
The basic local setup has user mailboxes on a variety of hosts inside
doc.ic.ac.uk. All local hosts share an aliases file with entries like
lmjm: lmjm@???
so we know where really to send email.
However as far as both internal and external users are concerned they
should only ever see
lmjm@???
the local host should not appear in the either the headers or any SMTP
envelope.
Under 0.52 this was all fairly easy to do with the attached configure
file (configure-0.52).
However this fails under 1.58. With the same configure file 1.58 thinks
that all local mail should be delivered on the local host! I'm guessing
it is applying the rewrite rules to the result of the alias lookup?
I've tried a variety of combinations and I can get pretty close but none
do all that I need (BTW how do you turn off Envelope-To: given that the
documented variable for doing it doesn't appear to work?) I've attached
a config' file (configure-1.58-almost) that rewrites everything but To
fields in the envelope. A test like:
Mail lmjm@???
sends the message to triumph under 1.58 using configure-1.58-almost.
Under 0.52 the message was, correctly, sent to swan. BTW If I add
rewriting To fields then exim goes back to trying to deliver mail on the
local machine.
Sincerely puzzled
Lee.
