Try telnetting to port 25 on one of their "*.hotmail.com" MX records. For example: ? host -a hostmail.com ... hostmail.com 651 IN MX 10 mc6.law5.hotmail.com ... mc6.law5.hotmail.com 383 IN A 216.33.238.136 ? telnet 216.33.238.136 25 Trying 216.33.238.136... telnet: Unable to connect to remote host: Connection refused ? Some of the MX records that show up for hotmail.com go to different machines, such as INKY.SOLINUS.COM which seems to let ECN connections through just fine. Later, David S.
