[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

  • Stefan,

    Outside of turning off tarpitting in Exchange, I don't know.

    It sounds like you have a commercial license, and thus have support.  If Sophos/Astaro gives you a solution inside the UTM, please post back to this thread.

    Cheers - Bob
