I don't think you are actually hitting against their mail servers for
your telnet attempts.

host mail.yahoo.com :

mail.yahoo.com is an alias for login.yahoo.com

host -t mx yahoo.com :

yahoo.com mail is handled by 1 e.mx.mail.yahoo.com.
yahoo.com mail is handled by 1 f.mx.mail.yahoo.com.
yahoo.com mail is handled by 1 g.mx.mail.yahoo.com.
yahoo.com mail is handled by 1 a.mx.mail.yahoo.com.
yahoo.com mail is handled by 1 b.mx.mail.yahoo.com.
yahoo.com mail is handled by 1 c.mx.mail.yahoo.com.
yahoo.com mail is handled by 1 d.mx.mail.yahoo.com.
