[EXIM] Odd sender verification problem

Running exim v1.82 (yes, I know. Upgrade.) on Solaris 2.5.1

For one of our customer domains, txsoft.com, I'm getting rejections. One
sample appears below:

------------------------------------------------------------------------------
1998-11-05 14:15:08 0zbUs8-0003N7-00 rejected from ns.infotechsys.com
[207.239.53.253]: no valid sender in message headers: return path is
<info@???>
Recipients: info@???
P Received: from ns.infotechsys.com [207.239.53.253] 
        by siren.shore.net with esmtp (Exim)
        id 0zbUs8-0003N7-00; Thu, 5 Nov 1998 14:15:08 -0500

          with SMTP id com for <info@???>;
          Thu, 5 Nov 1998 14:12:27 -0500
F From: info@??? <info@???>
T To: info@???
  Subject: TXSOFT - Free Subscription Application Form
  Date: Thu, 5 Nov 1998 14:12:30 -0500
  X-Mailer: Allaire Cold Fusion 3.1
I Message-Id: <E0zbUs8-0003N7-00@???>
------------------------------------------------------------------------------

However the address verifies.

> exim -bt info@???

jrogers2@???
    <-- jrogers2@???
    <-- info@???
  remote delivery to jrogers2@???
  router = localroute, transport = remote_smtp
  host shell3.shore.net [207.244.124.103] 

An exim -bs session run at -d9 doesn't list any reason why it's rejected
either. Cutting and pasting the above into the data section of an exim -d9
-bs shows that:

[massive snip]
Test
.
Data file written for message 0zbWZu-0004Cc-00

internal_search_find: file="/usr/local/etc/exim/reject.txt" type=0
key="sender_verify"
file lookup required for sender_verify in /usr/local/etc/exim/reject.txt
550-Sender info@??? verification failed.
550-Sender info@??? verification failed.
LOG: 3 MAIN REJECT
rejected: no valid sender in message headers: return path is <info@???>
550 rejected: no valid sender in message headers: return path is
<info@???>

So what plainly obvious thing am I missing here? I was thinking it might
have been lack of quoting on the body From: but I would have expected that
to yield a malformed header failure, not a sender verification failure.

Any ideas?

TIA,

Tabor
