How to deliver a nonlocal address locally

Hi,

I've experienced some problems with smarthost and automatical email
address rewriting quite similar to the ones described at
http://bugs.debian.org/309792

However my approach to a solution is slightly different, but let me
explain the problem first.

I've set up exim to deliver outgoing mail via a free mail service (gmx),
but then changed the account's password without telling exim. So all
outgoing mail was rejected by gmx and a delivery failure message was
generated by exim and now exim tried to send this failure notice to the
rewritten address (...@gmx), which of course also failed!

What happened then is that the failure notice got frozen and deleted
after two days, but it could have been delivered locally, if only I knew
how to tell exim that this particular email address (...@gmx) can be
delivered to ...@localhost instead.

How can I do this? How can I tell exim (exim4, debian, btw) to catch all
mails going to a given address (...@gmx) and deliver them locally to a
corresponding local address?


Btw. I noticed a line "freeze_tell = postmaster" in
/etc/exim4/conf.d/main/02_exim4-config_options which supposedly tells
postmaster about the frozen messages. Well, in short, it didn't. Is
there any possibility that this line was ignored, or does it have to be
activated by another switch?

This is the log entry for such a failure message:

add a router at the top of the routers section:

remote_local:
driver = redirect
domains = gmx.de
local_parts = steffen.wolf
data = the_local_username

-- snip --
message. If freeze_tell is set, Exim generates a warning message whenever it
freezes something, unless the message it is freezing is a locally-generated
bounce message. (Without this exception there is the possibility of
looping.)
-- snip --

Perfect! It works just fine. Thanks a lot.

Ah, that explains it. Sounds reasonable.
