That said, it seemed reasonable to implement a recent suggestion from the Postfix list and block XBL-listed IPs from connecting to my submission services. This had a rather noticeable effect on the rate of failed SASL probes. The suggested XBL check was added on May 27th, and recent counts of failed SASL probes per day were as follows:
IIRC XBL itself doesn't suggest to use it to block end users and my experiences shows that too. End users IPs are rotating/changing, especially on mobile connections, and you will block innocent users just because previously that IP was on bad device...
I used XBL for submission/IMAP about two years ago, but i abandon it due many false positives.
