That's it.
When you send an email to a recipient address containing one or several
8 bits characters, IMP (via Mail.php and RFC822.php from PEAR) shortens
this address to '<@>', and postfix forwards it to postmaster without
notifying the sender.

You must add the 'reject_non_fqdn_recipient' to the
'smtpd_recipient_restrictions' postfix parameter to reject the badly
RFC822 formed email. Then, the email client (IMP 3.0) will display an
error message.
Additionaly, if you have your MUA (IMP 3.0) and your MTA (postfix) on
the same host, you must configure the following Horde 2.0 parameters
(located in the 'config/horde.php' file) :

$conf['mailer']['type'] = 'smtp';
$conf['mailer']['params'] = array('host' => 'localhost');
