运行在CentOS 7服务器上的spring应用程序已经成功地将IMAP连接到CentOS 7物理服务器盒上由dovecot管理的Maildir收件箱。但是，在服务器上运行本OpenVPN教程中的一些脚本之后，应用程序就无法建立IMAP连接。脚本以不透明的方式改变了各种情况，包括DNS查找，因此不能完全逆转。

如何更改JavaMail代码，使其能够以不受服务器上运行的脚本更改的限制的方式成功连接到Dovecot/Maildir？

当应用程序试图通过IMAP连接时，引发的错误是：

代码语言：javascript
运行
复制
com.sun.mail.iap.protocolexception no login methods supported

抛出错误的代码行是：

代码语言：javascript
运行
复制
Properties props = new Properties();
props.setProperty("mail.store.protocol", "imap");
props.setProperty("mail.imap.partialfetch", "false");
String dirStart = "/home/import/xml/xmlimporttest/";
try {
    Session session = Session.getInstance(props, null);
    Store store = session.getStore();
    store.connect("host", "user", "password*");//this line throws the error
    //..other stuff
}catch...

完整的堆栈跟踪是：

为了进一步诊断这个问题，我输入了telnet mydomain.com 143并得到：

代码语言：javascript
运行
复制
Trying 127.0.0.1...
Connected to mydomain.com.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED] Dovecot ready.

然后设置session.setDebug(true);，这将导致在堆栈跟踪之前打印以下附加信息：

代码语言：javascript
运行
复制
DEBUG: setDebug: JavaMail version 1.5.0-b01
DEBUG: getProvider() returning javax.mail.Provider[STORE,imap,com.sun.mail.imap.IMAPStore,Oracle]
DEBUG IMAP: mail.imap.partialfetch: false
DEBUG IMAP: mail.imap.ignorebodystructuresize: false
DEBUG IMAP: mail.imap.statuscachetimeout: 1000
DEBUG IMAP: mail.imap.appendbuffersize: -1
DEBUG IMAP: mail.imap.minidletime: 10
DEBUG IMAP: trying to connect to host "mydomain.com", port 143, isSSL false
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED] Dovecot ready.
DEBUG IMAP: protocolConnect login, host=mydomain.com, user=username, password=<non-null>

在这些新的调试消息之后，与上面相同的堆栈跟踪紧随其后。

，这是否有助于隔离解决方案？还有其他事情我应该试试吗？

发出LOGINDISABLED命令之前的STARTTLS功能LOGIN。这意味着服务器被配置为通过不安全连接拒绝任何明文身份验证。确保从一开始就通过SSL/TLS连接(通常是端口993)，或者发送STARTTLS。请注意，您的系统上必须有可用的SSL库。
