I have dial-up connection to my ISP and need to rewrite addresses going to
the ISP. I have enabled the example rule in exim.conf, i.e.
*@localdomain ${lookup{$1}lsearch{/etc/email-addresses}\
{$value}fail} frsF
and set appropriate 'real' addresses in /etc/email-addresses.
However, this rewrites also the addresses for local deliveries in my LAN,
which causes local replies to be unnecessarily routed via ISP. Is there a
way to distinguish between local and remote deliveries and use this for
rewriting rules in exim.conf?
