It is indeed.

I've got "domains" set already.

Wouldn't that stop the chain of processing? I'm trying to accomplish this:
Incoming message -> Router A
Is it for domain A?
Yes -> Transport A
No
|
Router B
Is it for domain B?
Yes -> Transport B
No
|
Router C
Is it for domain C?
Yes -> Local delivery
No
|
Bounce message
Only domain C users have system accounts.
Here are the routers I have, in this order:
dnslookup:
driver = dnslookup
domains = ! +local_domains
transport = remote_smtp
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8
no_more
system_aliases:
driver = redirect
allow_fail
allow_defer
data = ${lookup{$local_part}lsearch{/etc/aliases}}
# user = exim
file_transport = address_file
pipe_transport = address_pipe
domainA:
driver = accept
condition =
${lookup{$local_part}lsearch{/etc/exim/${domain}.aliases}{yes}{no}}
domains = domainA
local_parts = lsearch;/etc/exim/$domain.aliases
retry_use_local_part
transport = domainA
domainB:
driver = accept
condition =
${lookup{$local_part@$domain}lsearch{/etc/exim/${domain}.aliases}{yes}{no}}
domains = domainB
local_parts = lsearch;/etc/exim/$domain.aliases
retry_use_local_part
transport = domainB
userforward:
driver = redirect
check_local_user
file = $home/.forward
no_verify
no_expn
check_ancestor
# allow_filter
file_transport = address_file
pipe_transport = address_pipe
reply_transport = address_reply
# This router matches local user mailboxes.
localuser:
driver = accept
domains = domainC
check_local_user
transport = local_delivery
/etc/exim/domains contains:
domainA
domainB
/etc/exim/domainA.aliases contains:
juha:
postmaster: juha@???
/etc/exim/domainB.aliases contains:
juha:
postmaster: juha@???
(Don't think this will work as an aliases file, but never mind about that
for now.)
