I believe, now you have proper logging level for normal work. I don't 
recommend you to decrease it.

The next (and the last) proposal is to check once more all your content 
filters, if you have ones. Both antispam and antivirus. First of all, no 
any content filters should be applied to "Postmaster" and "abuse" 
e-mail, just because mail to these addresses may and should contain 
evidences of malware and spam activity related to your system. Second, 
all these filters have false positives, and it would be more safe to set 
the filter to "quarantine" all suspicious messages instead of delete 
them permanently. Or, even better, reject during the SMTP session, with 
"5xx content rejected" after DATA end.

If you do so, you'll have 100% chances to find new delisting message 
tomorrow either in your mailbox or in the quarantine area, and good 
chance to see any futire abuse reports in your mailbox before your 
system end in blacklists ;-)

I go offline, it is 11 pm here an I had enough exercises in English for 
today...
Bye.
