Is it possible to set the spam filter not to send an email to the spam sender?

By default the spam sender gets a response which informs him, that his email has not reached the recipient. But: better is to send nothing to the sender of spam, so that he doesn't get any further information about the email system.

Is it possible to change this default behavior of spam email protection?

    In fact, it's not your email system that sends something to the sender when your system rejects his email, it's the sender's email system.  The only way you can avoid that is to accept every email.  This means setting 'Reject at SMTP time: Off', de-selecting 'Use recommended RBLs', emptying 'Extra RBL Zones', deselecting everything in 'Advanced Antispam Features' and then setting 'Confirmed spam action: Blackhole' to avoid having all that garbage come through.  That approach will use a lot of bandwidth and CPU cycles though.

    You don't say what your real concern is.  Maybe you just want to select 'Verify recipients: Off' on the routing tab.  Was that your concern?

    Cheers - Bob

    Thank you for your answer, then it has been my misunderstanding. I was thinking, that the response comes from sophos utm, that I got in a test. Then it is ok.
