From: mnb951 on 12 May 2008 15:11 Hello, I haven't recieved any response to my emails yet. I'm still having the same problem, If I try to telnet to port 25 on the exchange 2007 server I get the same error message, 421 4.3.2 Service not available, closing transmission channel. The server runs symantec endpoint security. Any suggestions?
