You can re-make that choice by running:

     # dpkg-reconfigure --priority=low exim4-config


In any case, it may be that those files are created even if you choose
the single file option (I don't actually know this for sure).

Look for /etc/exim4/exim4.conf - if it exists, that's the one you
should edit.

If you choose split configuration files, these are assembled together
to a single configuration file (/var/lib/exim4/config.autogenerated) by
the Exim startup script (/etc/init.d/exim4) as needed upon (re)start.

Do not modify the 00_ one. You _may_ modify the 31_ file. However, it
may be cleaner to create a new file, e.g. "50_local-config_rewriting".
That way, the stock file can be upgraded effortlessly by future
versions of the "exim4-config" package.

Usually, the sender address (both the "MAIL FROM:" envelope sender and
the address in the "From:" header line) are generated by the MUA,
irrespective of your MTA's host name.

That said, you should be able to do something like the following
(untested):

*@original-domain    $local_part@official-domain  Ffrs

The 31_exim4-config_rewriting does contain a hook suitable for this.
Simply add something like the following to your /etc/email-addresses:

     info: info@alternate-domain

The old (outdated) location was /etc/exim4/email-addresses.
The new location is /etc/email-addresses. (This file is, conceivably,
not Exim specific).
