Dear All, I receive some strange problems lately, my mailserver logs many CANT_MAKE_SMTP_CONNECTION.#4.4.1 So I took some domains from the logs and tried to examine the connection to each domains. What I did is I connect to internet using 2 connection, 1 my leased line conn, and 1 other ISP. and then tried to traceroute and telnet to port 25. There are some sites where I CANT TRACEROUTE using both conn, so I suppose the routing could be the problem, but from the ISP, I CAN TELNET to the site's port 25, in the other hand, I CAN'T TELNET using my own mailserver (leased line). It's strange to me. From ISP side, if it cannot traceroute, why it can telnet? Anyone can help me? Thanks! Chrisanthy
