Windows Mail extension

Description of the Windows™ Mail extension.

Send mail using MAPI

MAPI is an acronym for Messaging Application Programming Interface. The MAPI extension will create a new mail in the default mailer software, which needs to be "MAPI" compatible, and ask the user to send the mail. The mail sent using MAPI will be stored by the default mailer software in the same way as any other mail created by the user.

Send mail using an SMTP server

Another method of sending mail is to connect directly to an SMTP server (Simple Mail Transfer Protocol is the de facto standard for email transmission across the Internet). The extension will connect to a given SMTP server and send the mail through this server. The mail is not kept on the client side.
