[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
