* Mike:

   I've tried to get the attention of senderbase, which is claiming
activity from my address space which is in fact either un-routed or
within dynamic subscriber blocks that have outbound smtp filtering in
effect.

Could you share technical details on your filters, please?

If you only filter incoming TCP packets from your customers with
destination port 25, these filters might well be insufficient.
