If you are unsure of the name of the mail server for an email address, first try "mail.domain.com" or "smtp.domain.com". If niether work, try the following.

hotmail.com MX preference = 5, mail exchanger = mx3.hotmail.com
hotmail.com MX preference = 5, mail exchanger = mx4.hotmail.com
hotmail.com MX preference = 5, mail exchanger = mx1.hotmail.com
hotmail.com nameserver = ns1.hotmail.com
hotmail.com nameserver = ns2.hotmail.com
hotmail.com nameserver = ns3.hotmail.com
hotmail.com nameserver = ns4.hotmail.com
mx2.hotmail.com internet address = 18.104.22.168
mx2.hotmail.com internet address = 22.214.171.124
mx2.hotmail.com internet address = 126.96.36.199
mx3.hotmail.com internet address = 188.8.131.52
mx3.hotmail.com internet address = 184.108.40.206
mx3.hotmail.com internet address = 220.127.116.11
mx4.hotmail.com internet address = 18.104.22.168
mx4.hotmail.com internet address = 22.214.171.124
mx4.hotmail.com internet address = 126.96.36.199
mx1.hotmail.com internet address = 188.8.131.52

mx1.hotmail.com internet address = 220.127.116.11
ns1.hotmail.com internet address = 18.104.22.168

The "MX preference" specifies which mail server to use and in which order. The lower the number, the more preferred the mail server is. In this case, since the preferences for each mail server are the same, you can use any of the four "mail exchangers".
