on the imail box, can you telnet 66.34.234.34 25 it works for me: # telnet 66.34.234.34 25 Trying 66.34.234.34... Connected to 66.34.234.34. Escape character is '^]'. 220 mail1.wise-advice.com ESMTP Server (Microsoft Exchange Internet Mail Service 5.5.2653. 13) ready quit 221 closing connection Connection closed by foreign host. >I tried using the knowledge base, but nothing suggested there seems to >help.
