Check the following: double click connectors right click your outgoing SMTP connector select properties select address space tab make sure you do NOT have the "allow messages to be relayed to these domains" box ticked if you have a wild card smtp address i.e. SMTP * Have fun Don -----Original Message----- From: Wakelin, Frank [mailto:fwakelin@xxxxxxxxxxxxx] Sent: Friday, 12 July 2002 7:18 AM To: [ExchangeList] Subject: [exchangelist] RE: Exchange 2000 Relaying http://www.MSExchange.org/ Just a thought... Perhaps it was adding the local IP subnet that is still allowing the relaying. I'm assuming of course that your server is behind a firewall or proxy of sorts. Depending on the configuration of the firewall/proxy, the SMTP server may only be seeing the internal IP address of your firewall and therefore it would allow the relaying. You could turn on logging of the SMTP protocol, or sit at the console and do some "NETSTAT"s to see what connections are being made (if you know you have a lot of inbound internet email) to determine this. That would tell you for sure the source IP the server is seeing. I think the best idea was to leave the defaults. If you do need unauthenticated relaying (say for network management-type email alerts) then you should specify on the IP address of that server. Certainly don't specify the firewall as an IP to allow relaying though... ____________________ FRANK WAKELIN NETWORK ANALYST tel: (604) 640-4096 (direct) fax: (604) 687-1415 Email: fwakelin@xxxxxxxxxxxxx BORDEN LADNER GERVAIS LLP 1200 WATERFRONT CENTRE 200 BURRARD STREET P.O.

I have a windows 2000 server with exchange 2000 (both SP2). I have enabled the SMTP Virtual Server so that it does not relay. However, my ISP is telling me that it is still open. I have published the server through ISA 2000 SP1. Is ISA causing the problem by opening it up??? Once I have the relaying issue sorted, I need to install Norton for Gateways. Has anyone else had any problems with installing this. I have stopped all the exchange and SMTP services to make port 25 available when I install. However, after the install, I am unable to telnet to port 25. Your help would be much appreciated.
