Thanks, missed trying that variant.  Can't test right now...  I clicked
Trash on a couple of these messages; but now can't find them in the Trash
folder.

POP3S, no filter affects these messages, so they stay in the Inbox on
receipt. However, I expected to find them in the Trash folder intending
to use them to test; but nope...

Two possible reasons:
- No-date message is totally deleted on Trash click
- No-date message has a Date header added upon Trashing
Other?

The next time I get one of these messages, my current rule will only
change its color as a test.

Cheers,
Pierre
