[Mimedefang] Accessing the source/destination port #'s at filter_relay

[Philip A. Prindeville]

I'm trying to do some things with logging and calling into iptables/tc
early on during the lifetime of a connection, i.e. at filter_relay() time.

Is there any way to make this information available sooner than
filter_sender()?

If I'm going to tarpit the connection, I want to do it as early as possible.

Thanks.
