Hey Alibek,
From my testing on my lab environment, i was able to manipulate the email in the way so it forces the email to be sent to the spam quarantine of the sender address rather than recipient (which is the design).
However to do so, it requires altering of the actual email in the event the email is seen as positive spam you'll re-write the recipient so that it goes into the sender mail box, but by doing so when the email is released it will not release back to the original recipient but to the actual sender.
This type of behaviour is not with the system design so I went forward with mail manipulation to achieve the results desired (to an extent)
What this means is, for testing purposes (before you decide if you want to put this into production)
Create an outgoing mail policy for your test address to be using where sender is your address.
On the anti-spam settings, change positive/suspected spam to 'deliver' but add a custom header like X-IP-Spam or so.
Create a content filter where it will look for this header, and if the header exists.
Action would be
Change recipient to -> The sender address
Change mail destination host -> 'the.euq.queue'
Then enable this content filter.
What this filter does is, it will re-write the original intended recipient to the sender address when emails are seen as spam and will send it to the rewritten 'recipient' spam quarantine.
Thus will go into the spam notifications when generated.
Note: When you release this email, it will release to the rewritten recipient and not the intended recipient.
