i have a set up which doest exactly that
(and by the way i find that seting in the exim FAQ) :
begin routers
# Handle external domain,
# transfer with smtp
dnslookup:
driver = dnslookup
domains = ! +local_domains
transport = ${if match{$domain}{\N\your.internal.dom\N}{int_smtp}{ext_smtp}}
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8
no_more
begin transports
int_smtp:
driver = smtp
ext_smtp:
driver = smtp
headers_rewrite = *@your.internal.domain $1@your_external_domain
return_path = $sender_address_local_part@your_external_domain
If you have to spread this config over a lot of mail server,
you can use a DNS server,
i'm using DNS to have the same file on differant server,
and querying to check what are the internal and external name of
differant host VPNised,
i store this kind of information in a TXT RR in the form of
"ext_name=***"
