There are dozend of reasons why this can happen.
Most common is 'PenaltyExpiration'.
If there is a good mail transfered by an IP, the IP score is deleted to 
prevent false positives. Where good means - no doubed, like 'contentOnly', 
RWL, SPF, DKIM ....

Betreff:        [Assp-test] PB-IP-Score suddenly dropping



Hi all,

 

I just tracked some IPs through my logfiles just to see how they build up
their score. Something strange is happening:

 

Case 1: between 09:51:13 and 12:49:10 PB-IP-Score drops from 600 to 0
without any visible reason

I'm currently running  ASSP version 2.5.2(16270) on Debian with perl 5.22.
There have been no restarts or resets of ASSP for 6 days.

 

Any ideas what has happened here?

 

 

Best regards

Dirk
