We have been shipping with PSBL as a default enabled list for the last while, however I should point out my problem with having these in Spam Assassin. They belong in the SMTP layer first of all ;) and second.. as soon as you do, some sites that will be using it will use enough resources that all of a sudden we will find that PSBL will go the way of a lot of other lists and start charging those users.. or block access to PSBL and cause problems with email delivery.
As far as PSBL is concerned (other than our own lists :) I would have no problem voting +1 on PSBL based on our very low FP with that list. I dont think there is a single MagicMail server out there in use where the administrators are not using it as a recommended list. Currently, ISP stats show has the ability to block about 20% of inbound connections with a 2.3% unique count. (This could be higher, except we use rate limiters) This is about equal to SORBS-DUL, and RATS-NOPTR, but about 1/2 the UCE's and RATS-DYNA. However, we do believe the list is very safe for SA. (PSBL) I would first approach PSBL and see if they have any changes planned in the next year tho.
