Actually, no.. if you can telnet to the mail server you can relay. No hacking needed. This is by the very nature of exchange. I would recommend looking at not allowing characters like %$! Through your firewall. Here's a link to check to see if you have an open relay.. http://www.abuse.net/relay.html Thanks, Joe Irvine Director of Information Technology The Business Office, Inc.

Importance: Low Look at the 4031 error messages, which indicate SOMEONE is trying to relay through the server, and since unauthorized relaying is prohibited that tells me someone has hacked in. >-----Original Message----- >From: William Lefkovics [mailto:[EMAIL PROTECTED]] >Sent: Tuesday, July 16, 2002 1:03 AM >To: MS-Exchange Admin Issues >Subject: RE: Exchange 5.5 server HACKED! > > >Then it's sorta in production then, yes? > >Was there a concern other than the 4318's? > >-----Original Message----- >From: Dan Schwartz [mailto:[EMAIL PROTECTED]] >Sent: Monday, July 15, 2002 9:55 PM >To: MS-Exchange Admin Issues >Subject: RE: Exchange 5.5 server HACKED! > > > > Yes, it's connected, and the DNS servers have been pointed at it >for about a week... > >>-----Original Message----- >>From: William Lefkovics [mailto:[EMAIL PROTECTED]] >>Subject: RE: Exchange 5.5 server HACKED! >> >> >>Is it connected to the internet? >> >> >>-----Original Message----- >>From: Dan Schwartz [mailto:[EMAIL PROTECTED]] >>Sent: Monday, July 15, 2002 9:10 PM >>To: MS-Exchange Admin Issues >>Subject: RE: Exchange 5.5 server HACKED! >> >> >> >> The server is not in production yet: There should be NO SMTP >traffic on it. >> >> [The business owner is returning from vacation tomorrow >(Tuesday), and that's when I roll out the Outlook clients.] > > [Balance cut] > > > List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
