The BBS has been configured to reject WP bulletins, but yet, WP bulletins are still arriving with status
BK (bulletin killed), but why? I asked John G8BPQ and was given a helpful insight into how the forwarding protocol of choice can affect the message filters. After inspecting my BBS log file, he explained:
The WP messages that aren’t being rejected are all arriving via B2 protocol (FC proposal). The standard FC message doesn’t include
VIA so the filters have to kill filtered messages instead of rejecting them.
Between BPQ BBS systems the FC proposal is extended. Many of those messages are rejected, but not all of them.
