Subject: [isalist] Blocking access to mail.Yahoo.com
http://www.ISAserver.org
I want to block users' access to retrieve e-mail from their Yahoo.com
mail accounts and so I created a site and content rule to deny access to
destination set *.mail.Yahoo.com. That worked, but now we can't send
e-mail to anyone@xxxxxxxxx -- the mail sits in the outgoing queue in
Exchange and gives the following message: "the recipient was
unavailable to take delivery of the message." When I disable the above
site and content rule, the messages to anyone@xxxxxxxxx are delivered.
Is there a different way to identify the destination so that users
cannot access their own Yahoo mail accounts but we can still send mail
to anyone@xxxxxxxxx? Thanks in advance for your help!
