ASP sends mail with JMail and CDO

Some time ago has sent a simple jmail mail email code, today this code to make a specific annotation, and add two other formats of code, with a few simple examples:
The first is Jmail.smtpmail's core code:
<%
Set JMail = Server.CreateObject ("JMail. SmtpMail ")" Creates a JMail object
Jmail.silent = True ' JMail does not throw an exception error and returns a value of false and True
Jmail.logging = True ' Enable use of logs
JMail. Charset = "GB2312" The code for the message text is Simplified Chinese
JMail. ContentType = "text/html" The format of the message is HTML
JMail. ServerAddress = "server address" ' Sending a message
JMail. AddRecipient Email ' recipient of email '
JMail. SenderName = "SenderName" ' Mail sender's name
JMail. Sender = "Email address" ' e-mail addresses of senders
JMail. Priority = 1 ' Mail emergency program, 1 for fastest, 5 for slowest, 3 for default value
JMail. Subject = "Mail Subject" ' Title of Message
JMail. BODY = contents of mail body
JMail. ADDRECIPIENTBCC Email ' BCC Recipient's address
JMail. ADDRECIPIENTCC email ' cc's address
JMail. Execute () ' Send mail
JMail. Close ' Closes the mail object
%>
The W3 Jmail4.3 component has redesigned its internal structure--using the Message object instead of the original single object jmail.smtpmail sending mail, and some methods that require authentication (such as 163, Yahoo, etc.) can be resolved in the following ways:
<%
Set JMail = Server.CreateObject ("JMail. Message ")" To create an object to send mail
Jmail.silent = True ' Mask exception error, return False to true two value J
Mail.logging = True ' Enable mail logging
JMail. Charset = "GB2312" ' Text encoding for the message is GB
JMail. ContentType = "text/html" The format of the message is HTML format
JMail. AddRecipient Email ' Address of Mail Recipient
JMail. from = "Email from to Sender" ' E-mail address of sender
JMail. Mailserverusername = "UserName of email" ' User name required to log on to the mail server
JMail. Mailserverpassword = "Password of email" ' Password required to log in to the mail server
