Hello,On one of our servers our mail server is blocking some valid emails and in the exim log we see the following:
2017-12-15 14:44:57 1ePqIK-0007YL-Ox <= [email protected] H=host [1.2.3.4] P=esmtps X=TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256 CV=no S=198628 id=OFCEBF2372.91221910-ONC12581F7.004B703F-C12581F7.004B8711@domain.com T="Subject" from <[email protected]> for [email protected]

2017-12-15 14:44:57 1ePqIK-0007YL-Ox => discarded (system filter)
2017-12-15 14:44:57 1ePqIK-0007YL-Ox CompletedHow can we further analyze why this is happening? Which filter is blocking this email exactly?
