I use my email server to send email. I can send my emails to gmail successfully(I can find my emails in my gmail spam folder) but when I wand to send yahoo mail my emails is not recieved by yahoomail I check spam folder. but can not find it.
A:
I'm not sure here, but I think Yahoo might block some mails completely if it thinks they are spam, i.e. they won't even show up in your spam folder. While I'm not sure about Yahoo, I know that MSN/Live behaves this way.

My ip is not mapped to a valid domain name which i use in my email address. Do you think it is effective on yahoo blocking

Yeah, I'd think that Yahoo would block such mails completely. Maybe Yahoo's Help page for Postmasters gives you more information: http://help.yahoo.com/l/us/yahoo/mail/postmaster/
