㈠ 用javamail写的发送邮件 QQ邮箱为什么接收不了
有一段时间申请的QQ邮箱好像默认关闭了 pop3和smtp ,需要手动打开。你可以进入邮箱后点设置,然后点帐号,最下面有POP3/IMAP/SMTP服务,把这里面的两项都勾选就可以了。如果还是不行,请给我留言,呵呵
㈡ javamail 问题
报这样的错,是网络连接上的问题

㈣ 关于JavaMail读取邮件的状态问题
1、读取邮件状态要使用IMAP协议,POP3协议是看不到状态的,都是0;
㈤ javamail 出现550 User is locked。代码如下,求大神指教
服务器返回“550: Invalid User”、“550:local user only”或者“551 delivery not allowed to non-local recipient”。
如果出现在您使用普通方式发送邮件时,这是由于服务器对发件人地址进行检查,对于发件人地址不是由本服务器提供的邮件,不予已发送。
解决的办法是:打开Foxmail“帐户属性”中对话框,在“个人信息”的“电子邮件地址”中填写SMTP服务器正确的邮件地址。如果该提示出现在您使用特快专递发送邮件时,则表明对方的邮件服务器不接收这种特快专递的投递方式,请针对这次发送改用普通的方式。
