[exim] $sender_address no longer as in envelope

Hi,

on my new Gentoo Linux system my old non-Gentoo `exim.conf'
doesn't work any more. The messages are sent to my provider
in a form they do not accept.

The reason seems to be that the variables `$sender_address'
and `$sender_address_domain' changed:

  Former system:   bertram.scharpf@???
  Now:             root@???

I managed to authenticate to my provider by using `$domain'
and `$local_part@$domain' instead but then the sender
address still is "root@myrouter..." and the message is
rejected.

Maybe this problem is caused by the wrong Gentoo use flags.
I listed them below.

Any hints?

Thanks in advance,

Bertram
