From line creation? (2.2.4)

[Marius Strom]

Folks,
I've got a small issue with my 2.2.4 install of IMP.  It seems to be
adding a second From: header to outgoing messages.  Here is a sample
message:

> From "marius@alpha1.net"@mail.alpha1.net Tue Feb  6 10:55:07 2001
> Received: (from httpd@localhost) by mail.alpha1.net (8.10.1/8.10.1) id

The one that's got my curiosity is the first From
"user@domain"@imapserver <date>.

Relevant portions of defaults.php3:

$default->from_server = 'alpha1.net';
$default->to_domain = 'alpha1.net';
$default->custom_from_hook = false;

Relevant portions of imp_pref db for the account in question:
mysql> select user,fullname,replyto from imp_pref where user like
'marius%';  
+------------------------+--------------+-------------------+
| user                   | fullname     | replyto           |
+------------------------+--------------+-------------------+
| marius@localhost       | Marius Strom | marius@alpha1.net |
| marius@mail.alpha1.net | Marius Strom | marius@alpha1.net |
+------------------------+--------------+-------------------+

header.txt does not include anything with respect to the From line.

Other than mail.alpha1.net being in the sendmail.cw file, sendmail does
not otherwise know about that hostname.  (The FQDN of the mailserver is
/not/ mail.alpha1.net, so I don't gather that sendmail is tacking on
that header.. FWIW, sendmail would add a From: with a colon..)

Thanks in advance.
