Applying port 25 filters both ways (inbound and outbound to your
dialup pool, instead of just outbound port 25 filtering) would help in

Inbound 25 filtering has nothing to do with the situation listed above.

No, but inbound filtering *from* port 25 (to any port) does address the
problem, as I mentioned earlier in this thread.
