I'm currently using Outlook Express 5.5 and when I sent out a mass email using a BCC field, the names seem to have appear on the email rec'd by all the recipents. I noticed from one of the rejected emails with the following info:
From : firstname.lastname@example.org
To : <Undisclosed-Recipient:;>
Subject: Blah Blah Blah
X-Mailer: Microsoft Outlook Express 5.50.4522.1200
~~~~~All the mass mailing email address is being reflected here~~~~~~~~
*Appreciate if anyone could shed some lights on this. Thank U.
