[Exim] Sending to another local port

Hi!

I got a problem with Exim 3.33, where I suspect a too strong
restriction.

What I want to do, is having a small local Java socket listener
that handles some mails. It understands SMTP and should receive
some mails, being sent to localhost:2525.

However, I'd still like to have Exim listening on localhost:25

I've set up a transport like this:


smtp2525:
driver = smtp
port = 2525
allow_localhost

And a router like this:

route2525:
driver = domainlist
domains = "localcc.org"
transport = smtp2525
route_list = "localcc.org localhost byname"


I would expect things to work fine because of the "allow_localhost".
However, I does not:

route2525 router called for gvz@???
route_domain = localcc.org
routelist_item = localcc.org localhost byname
after handling route_lists items, matched = 1
original hostlist=localhost options=byname
expanded hostlist="localhost" options=byname
Unable to create IPv6 socket to find interface addresses:
error 97 Address family not supported by protocol
Trying for an IPv4 socket
Actual local interface address is 127.0.0.1 (lo)
Actual local interface address is 212.12.46.138 (eth0)

route2525 router: error for localcc.org
message: remote host address is the local host
gvz@??? cannot be resolved at this time:

Any chance to get this running, or is this impossible with
Exim without giving up the localhost:25 listener?

Merry Chrismas,
