You should be able to look at the internet header of the message to determine what address it was sent to. You could also use the message tracking centre within Exchange 2000 admin tools to track the message (assuming you have message tracking turned on). Basically, what you need to do is block internet email from reaching the group or restrict who is allowed to send mail to that group. You could look at your global address list (within an Outlook client for example) and find all of the groups. You could also perform an LDAP search within Active Directory for all of the mail enabled groups. Once you've found them check the SMTP address of the group(s). You could remove the external email address of that group (assuming you have an internal - external domain naming system in place for controlling internet email), or if that's not possible restrict who can send mail to that group (IE internal users only). --- Hope his helps -----Original Message----- From: Lazor, Ed [mailto:ELazor@xxxxxxxxxxxxxx] Sent: Friday, July 12, 2002 10:51 AM To: [ExchangeList] Subject: [exchangelist] RE: How'd they do that? http://www.MSExchange.org/ Thanks for the response, Frank. I'm really new to Exchange. Could you go into more detail? -----Original Message----- Perhaps a mail-enabled security group (like perhaps Domain Users)??? ____________________ FRANK WAKELIN NETWORK ANALYST **************************************************************************** This message is intended for the sole use of the individual and entity to whom it is addressed, and may contain information that is privileged, confidential and exempt from disclosure under applicable law.
