How to send email to ybb.co.jp?

i had a friend from japan gave me his email like this
" xxx.****@ybb.co.jp " tried sending but failed. no such server according to the mail reply.

i did some research, ybb.co.jp it seems associated with Yahoo Broadband in japan. quite complex system. anyone can help to clear my doubts? is my friend's email wrong? with the " xxx " in front of his email?Thanks in advance

I cannot say anything about the part before the @, but you might want to try:
@ybb.ne.jp
and see if it goes through.

hey, thx for helping, just wanna ask is that kinda email is to do with phone email?

still failed :( , i assume he is not giving wrong email. but i wonder why i cant send at all.

@ybb.ne.jp is a PC email account for Yahoo! ADSL users.

You can also try @yahoo.co.jp (Yahoo! free email address, like @yahoo.com in US).
If the recipient is a Yahoo! ADSL user, both addresses should work same way.

Neither has to do with phone email.

can i ask something...??how can i send e mail to my korean friend..??i had already tried sending him but still it is failure..pls help me

How does it fail?

according to mail reply their no such server...whats wrong with it.?

Possible reasons are: mail address is wrong, mail service was discontinued, mail server is out of order for a long time, etc.

What is the mail address (only after @)?
