I've been playing around with a few email programs in Kixnux latelt, sending myself test messages, etc. so it's a little difficult for me to remember what I have done and to make matters worse, I've deleted many items in sent items folders...

This morning I recieved a message which I have no recollection of sending and can't find anything in the sent items folders (but see above)... I checked the headers which are:

The line that really gets me is the one that starts "X-RBL-Warning". Can someone please explain what happened here and why the spam block on 24.98.172.83 crops up?
