I can send email from my domain but any incoming email gives an Address Unknown error in the smtp log.

Sending email address receives bounce back with message

The error that the other server returned was: 550 550 Address unknown (state 14).

Astaro box has joined my domain.

I have searched without success for an answer so any direction would be appreciated.

Brian, do you have anything between your Astaro and your mail server?

Just a network switch.

The only reason that the Astaro box would join your domain is to allow SSO authentication fir the HTTP/S proxy. That's unrelated to the behavior in email.

Try changing 'Verify recipients' to "with callout."

The log I posted was using 'with callout' I also test 'in active directory' and got a similar message. When I tried turning off verify recipient I didn't receive an error in the log but the message was never delivered.
I should also let you know that this is a new install of exchange 2007. I am also trying to find out if my problem may be with exchange and not with astaro.

I would suggest a couple of things to check, presuming you are using 'simple' mode and not SMTP Profiles:

- in your routing tab: is mycompany.com listed in 'domains' and is your Exchange server listed in the ' host list' ?

- Is your exchange serve configured to accept e-mail (requests) from the astaro box (trusted hosts I think it is called)

To see if it is possible at all to communicate between astaro and your exchange server, ssh to the astaro and try the following commands:

telnet <your Echange server> 25

you should receive something which ends in:


220 <your exchange server > .... ready

Then type QUIT to stop the session


If that does't happen and you get a 550 (denied) then your exchange server does not accept SMTP from astaro, so that could be the cause as well.

Hope this helps

Thanks for the tips. My Exchange server is not accepting SMTP from Astaro so I have some configuration left to do on my Exchange server. I will post an update when I get communication established between the two.
