Hi,
I am running exim as an email gateway and have a problem with a few spam messages. The gateway itself does currently no content checking and is just forwarding any message as long the recipient is valid. However the destination server might reject some messages based on it’s own spam filter. For most messages that works fine, that means that in case the destination server rejects a message, exim creates a NDR to the sender and drops the message.
Only with a few messages, exim freezes the message after delivery error and does not create a NDR, it’s continue trying to deliver.
Here are some details:

Does anybody has an idea what could be the reason for this message to behave different than others?
Thanks,
