I was the one who had that problems. My problem was that I wanted to send a simple e-mail and PC where using Lotus Notes, Outlook, Eudora and others.

I have success using winsock and the SMTP protocol. See the site http://nswt.tuwien.ac.at/htdocs/Connected/RFC/821/index.htm which contains the a document (written in august 1982 - almost 17 years past) which explains how you can fetch and send mail.

You also check here using the calendar view, the thread that was discussing it (check for the thread name "Sending a message" which ended on november 13).

I didn't use this techniques to read, nor I have include attachments, but I remember that you can.

Hope you'll have fun!!!
