This is unrelated to PBL or the respective SA rule.

The problem is, that all SMTP servers in the chain are in your internal
network, including the user's outgoing SMTP. Given the user's outgoing SMTP is
considered internal, the handing-over IP *is* the user's IP.

In such a case, actual botnet spam is indistinguishable from users submitting
directly into your internal network.

While I admit this is an issue, unless the SA network settings are carefully
set up, and/or the user's outgoing SMTP is distinct from your inbound MX --
IMHO this is not a bug.

Closing. Please feel free to re-open, if you still believe this to be a SA bug.
