Re: Best way to catch "no ^From:" spam?

Jim Osborn suggested to Jeff Schaller,

| Here's the recipe I use:
| 
| :0 H:
| * ! ^From:
| $TRASH
| 
| :0 H:
| * ^From: *$
| $TRASH

You can combine those two into one.  Also, it has a couple vulnerabilities: a
From: line consisting only of tabs would pass, while a message with one valid
From: line and one invalid one would be sent to the trash folder.

 :0: # H is implicit in the absence of B
 * !^From:.*[^  ]
 $TRASH

The brackets enclose caret, space, tab.
