Peer2Mail

Peer2Mail lets you store and share files on your web-mail account. If you have a web mail account with large storage space, you can use P2M to store files on it. Web-mail providers such as Gmail (Google Mail), Walla!, Yahoo and more, provide storage space that ranges from 100MB to 2GB.

P2M splits the file you want to share/store zips and optionally encrypts it. P2M then sends the file segments one by one to your account. Once P2M uploaded all file segments, you can download them and use P2M to merge the segments back to the original file.
