Optional pointer to the recipient or sender's address; this address is provider-specific message delivery data. Generally, the messaging system provides such addresses for inbound messages. For outbound messages, the lpszAddress member can point to an address entered by the user for a recipient not in an address book (that is, a custom recipient).

The format of the address is address type:email address. Examples of valid addresses are FAX:206-555-1212 and SMTP:M@X.COM.

fuck!太坑了。
