Personally, I use zen.spamhaus.org
You can use *any* RBL - just do not block mail, if you do not want to lost
mail. Try to impose delay 20s after every SMTP command if sender sits in RBL.
Most spammers will not deal with such slow server.

Example:

acl_check_connect:

   warn
        dnslists          = zen.spamhaus.org
        set acl_c_delay   = true
   ...
   ...
   accept
        set acl_c_wait = ${if def:acl_c_delay {20}{0}}
        delay          = ${acl_c_wait}s



and in every ACL add this instead plain accept:

   accept
        set acl_c_wait = ${if def:acl_c_delay {20}{0}}
        delay          = ${acl_c_wait}s
