This is in the nature of a final comment. I did wonder whether it's worth resurrecting this topic but I despair of the Junk Mail filter in Mail. No matter how many times I tell it the sender is or is not junk (or fiddle with the junk settings, reset the filter and re-train it or add it the sender to Contacts (again)), the damn thing won't learn.

The one thing that has worked is the Rule in relation to Facebook notifications, now up to 51, including one referring to my son who has been a Friend for many years as well as sharing my DNA.

I don't get that much junk and, rather than routinely checking the Junk mailbox for mis-filtered emails, I think I might just turn the filter off altogether and delete junk from the primary Mailbox as it arrives. I'll not miss anything important then.
