However, returning to the original message that prompted this enquiry I have

This message had, as far as I can tell, a valid From: header and it passed
through Spamassassin via Amavisd directly from Postfix. Nonetheless, it has a
MISSING_FROM tag.
Very strange. That (not surprisingly) does not hit MISSING_FROM in my test
environment.
If you add some trivial body to it just to keep the structure correct (or,
better, grab the entire original message) and test it from the command
line, does it hit MISSING_FROM again?
Is this only happening to messages sent via SquirrelMail? Is it
*consistently* happening to messages sent via SquirrelMail?
How is SA glued into your mail system? I see Amavis headers.
Check your Amavis config. You might also ask this question on the Amavis
Users list...
The only things I can think of are wild-ass guesses like mixed line
endings in the headers breaking parsing, or headers being removed by
Amavis or whatever passes the message in to Amavis, and then being put
back in after scanning, and those all seem highly implausible.

...intellectuals have no interest in what _creates_ wealth, and
what _inhibits_ the creation of wealth. They are very concerned
about the _distribution_ of it, but they act as if wealth just
exists somehow. It's like manna from heaven, it's only a
question of how we split it up. -- Thomas Sowell
