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,
