[9.002-12]Undeliverable: Mails are Qarantained as SPAM

[9.002-12]Undeliverable: Mails are Qarantained as SPAM


I do not understand the behaviour of SPAM detection.

When emails get send to nonexisting users my email server generates an undeliverable message.

The reply of my email server gets immediately Quarantained as SPAM in the ASTARO

When i look into the emai, the sender is 

but in the SMTP-LOG the sender is <> 


An exception to  is not working for anti spam detection.

The only way how I can enable Undeliverable mails is disable scan of outgoing mails !!!

Can anybody explain what happens

    your recipient verification is not working correctly, if the recipient@yourdomain.com is not valid, your ASG should not deliver that email to exchange

    Hi, i had the same issue and temporary solved it like below.
    I would be happy to have any feedback on this aswell.
    Whats the best practice with v9 and Exchange 2010 ??
    After that config i get a 550 back for unknown users and no NDR will be sent by exchange anymore.

    Go to the Blocked Recipients tab and select:
    Block messages sent to recipients not in the Global Address List
