Astro, exchange, ad combination failing

rizzah
Hi,

I been messing with this for hours now and im just going in loops, so i need some help :-)

I have a small test network, 1 DC/AD, 1 echange 2010, 1 astaro firewall. Mail is comming into the astaro and then send to the exchange server. I have created an active directory and when i run the tests it works just fine. with smtp settings i have set it to use the active directory for receipient verification. However whenever i send a mail to a user in the domain it gets bounced with "530 5.7.1 Client was not authenticated".  This error is coming from the exchange server im sure, and whenever i google on this error they all say i have to enable Anonymous mode in the hub transport settings. This works, but then it doesnt check anything anymore and it will allow mails from non-excisting email addresses aswell. 

Am i forgetting something ?

Thanks a bunch for any tips!

    If it works with 'Very recipients' set to "With callout", then don't bother with the "In Active Directory" setting.

    Cheers - Bob

    Seconded. While active directory is an interesting way of approaching the problem, callout is simpler & easier. To my understanding it uses smtp to verify the recipient so if that doesn't work your email server is most likely down and you have bigger problems then possible spam.
