Have you thought to get more e-mail addresses on the same isp or
even in other sites, possibly using the same mailbox ? (That is:
You get acoplast-1@??? acoplast-2@??? and so
on. For the provider it is just a line in aliases file, or you could use
for private mail some free e-mail provider, forwarding all these e-
mails to the only one mailbox you have, so fetchmail or any other
program you use could automatically distrubute inside.
Also, since you would have all unique addresses both in and out,
you could set the gateway mailer to recognize all these address,
and deliver locally according, without need to rewrite.
(more expert EXIM users should tell us how to do: the program
must make a lookup in an alias file with full qualified addresses ,
and then making local deliveries based on that addresses, then
process all other messages sending to the external smarthost

It is unclear if you configured the exim server to deny relaying. In
your configuration it would be better to let it accept all from the
local hosts, inclusive of localhost !
I think is this the problem that forbide you to work.
Also you do not say WHAT of the many server ( the internal, the
secondary, the ISP one ?) refuse to go ahead !!!
