just query the dns for a mailserver record

Example for windows

You have the address
example@google.com

you can then search for a mailserver with a dns query
nslookup -type=MX google.com

this returns a list of all mailservers where you can send emails ending in @google.com
google.com      MX preference = 10, mail exchanger = aspmx.l.google.com
google.com      MX preference = 20, mail exchanger = alt1.aspmx.l.google.com
google.com      MX preference = 30, mail exchanger = alt2.aspmx.l.google.com
google.com      MX preference = 50, mail exchanger = alt4.aspmx.l.google.com
google.com      MX preference = 40, mail exchanger = alt3.aspmx.l.google.com

aspmx.l.google.com      internet address = 64.233.184.27
alt1.aspmx.l.google.com internet address = 64.233.162.27
alt2.aspmx.l.google.com internet address = 74.125.200.27
alt4.aspmx.l.google.com internet address = 173.194.72.27
alt3.aspmx.l.google.com internet address = 74.125.23.27


lowest preference = highest priority when using the mailserver.

You can then connect by using the standard smtp ports (25 for unencrypted connection) and send the smtp data to the server. That's basically what any mailserver does anyway when sending a mail to an address outside of it's scope.
