In this paper we propose an integration between electronic mail and web services for people such as library operators who need to send large files to Internet users. The proposed solution permits librarians to continue using the e-mail service to send large documents, but at the same time overcomes problems that users can encounter downloading large size files with e-mail agents. The library operator sends the document as an attachment to the destination address, on fly the e-mail server extracts and saves the attachments in a web-server disk file and substitutes then with a new message part that includes the URL pointing to the saved document. The receiver can download these large objects using user-friendly browser.
