I’m grateful for SpamSieve but really really wish that it had two features.
and absolutely sovereign white list so that ANY mail that has the “from” field containing @myuniversity.edu is NEVER marked as junk. Even people who regularly write from this address (like my wife!) get spammed every so often. I always correct it, but a month or so later one of my students or my wife shows up in junk. This has been a regular problem for some years.
a way to interact easily with the rules of our mail programs so that mail from say, the pseudo-FedEX International goes directly to trash. Having scores of messages to cull through in the spam folder is not entirely a solution.
