用javamail发送邮件aistill(原作)

关键字javamail,smtp,附件,HTML邮件,smtp认证

/*

在java版常常看到有人问若何用javamail发送邮件?若何接管邮件?若何造访多个文件夹等。问题琐屑,而历史的回覆早已经淹没在问题的海洋之中。

本人之前所做过一个java项目,此中包孕有WebMail功能,当初为用java实现而对javamail摸索了一段光阴,总算有点劳绩。看到论坛中的常常有此方面的问题,是以把我的一些履历帖出来,盼望对大年夜家有些赞助。

此篇仅先容用javamail实现发送邮件功能,此中涉及smtp认证,邮件附件发送,及HTML内容邮件等。

其它有关多邮箱的实现,接管POP3邮件及IMAP等内容,将在后续文章中先容。

如下法度榜样必要:javamail,JAF包,j2ee.jar包孕了上述两个包,建议大年夜家安装J2SDKEE或直接拷贝j2ee.jar,将其添加到jbuilder的library中,或系统ClassPath中
