ssl security
SSL is a transport-layer security protocol, that encrypts data between the network source and destination based on keyed encryption. Once that data is received by your web server, from a network standpoint, SSL's job is done, and any transferred data that is process by IIS will be processed and stored in the clear. If you want to secure the data past that point, you need to look into something like PGP, which could possibly be used in conjunction with an IMAP or SMTP client to re-encrypt the data on the disk and e-mail that encrypted data to the recipient (you), who would then decrypt it a
second time using the same software.
