详细讲解PHP的Jmai组件及发送邮件实例

<%
On error resume next
Dim JMail, contentId
Set JMail = Server.CreateObject("JMail.Message")
JMail.Charset = "gb2312" 邮件字符集，默认为"US-ASCII"
JMail.ISOEncodeHeaders = False 是否进行ISO编码，默认为True
发送者信息（可用变量方式赋值）
JMail.From = "webjxcom@163.com" 发送者地址
JMail.FromName = "网站管理员" 发送者姓名
JMail.Subject = "邮件主题" 邮件主题
身份验证
JMail.MailServerUserName = "webjx" 身份验证的用户名
JMail.MailServerPassword = "webjx" 身份验证的密码
设置优先级，范围从1到5，越大的优先级越高，3为普通
JMail.Priority = 1
JMail.AddHeader "Originating-IP", Request.ServerVariables("REMOTE_ADDR")
加入一个收件人【变量email：收件人地址】可以同一语句重复加入多个
JMail.AddRecipient("5ss@163.com")
加入附件【变量filename：附件文件的绝对地址，确保用户IUSR_机器名有访问的权限】
【参数设置是(True)否(False)为Inline方式】
contentId = JMail.AddAttachment (Server.MapPath("jmail.asp"), True)
邮件主体（HTML(注意信件内链接附件的方式)）
JMail.AppendBodyFromFile(Server.MapPath("/Love/Inc/Mailend.txt"))
JMail.HTMLBody = "<html><head><META content=zh-cn http-equiv=Content-Language><meta http-equiv=""Content-Type"" content=""text/html; charset=gb2312""><style type=text/css>A:link { FONT-SIZE: 9pt; TEXT-DECORATION: none; color: #000000}A:visited {FONT-SIZE: 9pt; TEXT-DECORATION: none; color: #666666}A:hover {COLOR: #ff6600; FONT-SIZE: 9pt; TEXT-DECORATION: underline}BODY {FONT-SIZE: 9pt} --></style></head><body><font color=red>邮件正文</font><br><font color=green>邮件正文</font><br><b>邮件正文</b></body></html>"
邮件主体（文本部分）
JMail.Body = "我们的邮件采用了HTML格式，但是您的邮件查看软件可能不支持。。。邮件正文,邮件正文,邮件正文"
发送【调用格式：objJMail.Send([username:password@]SMTPServerAddress[:Port])】
JMail.Send("smtp.163.com")
关闭并清除对象
JMail.Close()
Set JMail = Nothing
if err.number<>0 then
response.write "发送发送失败！"
else
response.write "邮件发送成功！"
