Until very recently Thunderbird offered the option to print or print preview an email. This now isn't available - oh, hang on, seems to be working again?
With Windows Mail you can look at the source of the email without opening it to check if the alleged originator is correct, and not some SPAMmer.
Print preview seems to be the main option to do this on T'bird (no doubt there are other ways).
I'm now baffled (as usual) because the feature was greyed out but is now back.
Humph!
