无法收到来自Apache James的电子邮件 [英] Can't receive emails from Apache James

问题描述

我开发了一个网络邮件来链接apache james，它可以工作.但是某些用户无法收到来自james的电子邮件.我设置mailSession.setDebug(true)并跟踪两个用户的日志(一个可以接收，另一个不能).区别如下所示:

I developed a webmail to link apache james and it works. But some user cannot receive emails from james. I set mailSession.setDebug(true) and trace two users' logs(sa can receive, the other cannot). The difference shows below:

可以成功接收电子邮件的用户(用户sa):

the user who can receive email successfully(user sa):

[2012-11-15 14:24:12] com.csc.mail.jsh.mail.core.ReceiveMail : [INFO ]  - trying to receive emails from james server...
C: STAT
S: +OK 2 2584
C: NOOP
S: +OK
C: TOP 1 0
S: +OK Message follows
...

其他用户接收失败(用户柴):

the other user receive failure(user chai):

[2012-11-15 14:22:01] com.csc.mail.jsh.mail.core.ReceiveMail : [INFO ]  - trying to receive emails from james server...

我的接收代码:

Session mailSession = Session.getInstance(System.getProperties(), null);
mailSession.setDebug(true);
Store store = null;
Folder folder = null; //javax.mail.Folder
try {
    store = mailSession.getStore("pop3");
    store.connect(Property.getPop3(), userName, password);
    logger.info("trying to receive emails from james server...");
    folder = store.getFolder("INBOX");
    try {
        if (!folder.isOpen()) {
            folder.open(Folder.READ_WRITE); //the point of throwing the exception
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    //receive email from james server.
} catch (Exception e) {
    logger.error("Email Receive Error!" + StackTraceStr.st2str(e));
    try {
        folder.close(true);
    } catch (Exception e2) {
    }
} finally {
    try {
        store.close();
    } catch (Exception cloex) {
    }
}
