Problem solved:
While somebody in the world, send mail to user admin@domain.external,
MTA reroute it to admin@domain.local by "external_to_local" router (it
rewrite recipient in DATA section) and dovecot delivery it to mailbox of
local user.
If some local user write to another local user in local corp. domain,
it not rewriting or rerouting, just used "localuser" router.
If some local user writing mail to external world, used "dnslookup"
router, it use "ext_smtp" transport.
This "ext_smtp" transport rewrite sender and return path to my
external domain by searching in "alias file".
Aliases file example:
---/usr/local/etc/exim/rewrite_external.lst---
admin@domain.local admin@domain.external
administrator@domain.local administrator@domain.external
---
---/usr/local/etc/exim/rewrite_local.lst---
admin@domain.external admin@domain.local
administrator@domain.external administrator@domain.local

pipe_transport = dovecot_delivery
localuser:
driver = accept
domains = +internal_domains
transport = dovecot_delivery
cannot_route_message = Unknown user
dnslookup:
driver = dnslookup
domains = ! +internal_domains : ! +external_domains
transport = ext_smtp
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8
no_more
-----------------------------------------------------------
begin transports
ext_smtp:
driver = smtp
headers_rewrite = *@+internal_domains
${lookup{$0}lsearch{/usr/local/etc/exim/rewrite_external.lst}{$value}fail}
return_path =
${lookup{$return_path}lsearch{/usr/local/etc/exim/rewrite_external.lst}{$value}fail}
dovecot_delivery:
driver = pipe
command = /usr/local/libexec/dovecot/dovecot-lda -d
$local_part@$domain -f $sender_address
message_prefix =
message_suffix =
delivery_date_add
envelope_to_add
