I have already started similar thread here viewtopic.php?f=13&t=63828
...but unfortunatelly it is kind of urgent, as mail items are disappearing randomly and many without trace.
Symptoms:
Users are complaining, that after upgrading ZCS to 8.8.7 they simply miss some of incoming mails.
Some even say, that they could swear they actually saw particular mail already in inbox, but later could not find it anymore.
Technically:
In /opt/log/zimbra.log I can see such entries for REAL SPAM:
Code: Select all

Not in /opt/zimbra/data/amavis nor anywhere else.
I looked up into particular USER ID in /opt/zimbra/store and messages are NOT there.
I am lost and becoming desparate...what can I do?
If I disable Amavis, there will be a lot of real spam.
But something obviously changed with upgrade to 8.8.7, rendering Amavis and underlying algorithms to be too strict and to simply DISCARD the incoming messages, rather than marking it as SPAM.
