It's now ready for testing by other people.
If you are interested in this at all, please do give it a try, as it

The download links are these:
The ChangeLog tells you about it a bit, and if you look in the
MailScanner.conf file for "Archives Are" and all the new options at the
end of the same section, you'll find it all.
Please test it for me!
