email client
 

I want to design an email client for gmail and yahoo. Somebody suggest me how to do this ??

I remember a saying from somewhere. It was similar to:

"Have a new idea for an application? Great. Join one of three projects already implementing it."

The idea was to promote having a few strong programs in the Hurd for a task instead of many weak ones.

I recommend you instead look into Thunderbird or mutt.

If you are set on rolling your own, identify what operating system(s) it will run on, whether it will be terminal or GUI based (and then which dependencies), and which features you want included.

Pretty much any email client available for Linux can do this already, and there are lots of how-tos on how to set them up.

If you want to write your own, follow the advice Sky.Crawler gave you. You also have to research how IMAP/POP email clients work, and implement those standards in your code. Not sure what you're asking people to suggest...if you want to know how to write a computer program, that's a broad question.

I have used Evolution in my ubuntu system. I want to add some features to this.
