I've tried the directions as above for postfix, however any mail sent through
this server to internal mailserver doesn't get there, it gets rejected:

notes: mailscan is the hostname of this machine, is it natted behind a
sonicwall appliance, domain.com replaces the real domain name in the logs
below.  Sibbleh at mailscan.domain.com is an exising account (and only uers
account other than root) on this relay box.

Harondel.J.Sibble at domain.com is an existing account on the internal
mailserver that mailscan relays to.  The mailscan box does not have an MX
record currently, just an A record as it is just in testing phase and which
is why I am emailing to username at mailscan.domain.com rather than
username at domain.com.

outbound03.telus.net[199.185.220.222]: 450

table; from=<help at pdscc.com> to=<Harondel.J.Sibble at mailscan.domain.com>
proto=ESMTP helo=<priv-edtnes11-hme0.telusplanet.net>

However if mail is sent to a local account that exists on this relay box,
then all is good...

Dec 31 18:21:37 mailscan postfix/nqmgr[5528]: 428F46F58A:

to=<sibbleh at mailscan.domain.com>, relay=local, delay=24, status=sent
("|/usr/bin/procmail -Y -a $DOMAIN")

The relevant lines from my /etc/postfix/main.cf

local_recipient_maps =
relay_domains =
transport_maps = hash:/etc/postfix/transport

the contents of transport are

domain.com       smtp:nat ip address of internal mail server


The second problem is mail sent from the internal mailserver gets relayed
properly except for mail addressed to domain.com addresses. These get bounced
back by the relay box to the internal mail server with a 550 spam block
message.

Any suggestions on where I should be looking to resolve these 2 issues?
