Hmm P V Vithlani .. Welcome to the Forum ..

..
Well .. Please be elaborate in asking the question

.. I mean which Email service you use ..? If you need to know Yahoo's Servers then they arent availible .. Yahoo has stopped giving POP3 support for free accounts .. If you want to access Yahoo mail from your email manager then either you'll have to use third party tools like Yahoopops .. or sign up for the paid service ...
Btw .. you can have a look at this thread for more options ..
