Few days back i needed to copy all the email addresses and names of the senders from yahoo mail account and the thing to note is that the number of mail were over 10 thousand. And I needed to copy all of them in excel file format. So I started building an application that will be able to grab all the mails one by one and extract the email ids and names. So that i could put them all in excel file. Right now I am working over it and will complete probably in a day or two. Application will be available to download soon.
