[PLUG] sendmail question - sending null ORCPT

I have encountered an apparent oddity in my Sendmail configuration. Please,
hold off on the "switch to postfix/etc" suggestions - that is in the future
plans, but for today I am stuck with Sendmail and I need to fix this issue.

When communicating with a remote MTA, trying to submit new mail, my
installation of Sendmail on openSUSE 10.3 is giving a bogus RCPT command.
Like so:

RCPT To:<1 at 2.3> NOTIFY=FAILURE ORCPT=rfc822;

when it should look like so:

RCPT To:<1 at 2.3> NOTIFY=FAILURE ORCPT=rfc822;<1 at 2.3>

I'm not entirely certain whether the <>s are supposed to be present in the
ORCPT command, but in any case, there's nothing there.

Any idea where I can start to look for why it's blank?

SMTP transaction snippet (via packet captures):

local.58189-remote.00025: RCPT To:<1 at 2.3> NOTIFY=FAILURE ORCPT=rfc822;
DATA
remote.00025- local.58189: 501 5.5.4 Invalid arguments
remote.00025- local.58189: 503 5.5.2 Need rcpt command


thanks,
