We have a Exchnage server for only   Server has NT4, IIS4, DNS.   How Do I use TCP IP security tab to configure security so that all the unnecessary ports are closed, we only use exchnage for POP3 and SMTP.   The last time I tried I got Max user limit .... on SMTP     Many thanks, List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
