How to do a filter for a recurring blank email

[bob hewson]

How to do a filter for a recurring blank email which I receive frequently. The message has no sender, subject or message and appears as a blank message.

There is a lot of info in the header, but I can't figure what info to put in the filter as sender or domain to blacklist.

The header info is below.

Any suggestions would be appreciated

Thanks,

Bob

So there's no Subject line in the header ?

I would probably start there, a simple, if the Subject doesn't contain Regex . <- That's a fullstop to indicate any character.

You could also look at the Received-SPF: softfail

You can also use the "does not contain" an "@" in the To: or From: fields.
