Unable to send outbound mail via smtp - 31.Jul.2006 9:26:44 PM

I've installed exchange on an AD machine in hub transport role and am trying to use it without an edge transport server. I've managed to recieve e-mails from other domains, but so far i've only been able to send outbound e-mails via outlook web access. If i connect via telnet/outlook to the smtp service, i'm getting an error saying client is not authorised to send as this sender.
from telnet:
mail from: someone@anyexternaldomain.com
sender ok

but if i specify:
mail from: user@mylocaldomain.com
client is not authorised to send mail as this sender.
I'm assuming the send connector is working because when i disable it, e-mails sent via web access will not work too.
I've also tried placing a .eml in the pickup folder, but this did not get sent (file remained in the pickup folder) any ideas pls ?

Since the Hub Transport Server only is allowed to submit messages to an Edge Server in the perimeter network, you need to issue below CMDlet:

get-receiveConnector server1\default* | set-receieveConnector -permissionGroups "AnonymousUsers,ExchangeServers,ExchangeLegacyServers,AnonymousUsers"

This is in order to be secure by default.
