Java imap 连接存储带和不带 ssl

Question

我正在尝试连接到基于用户服务器的 imap 商店。例如，我有多个服务器，例如 143 个带 ssl 的服务器和 993 个不带 ssl 的服务器。当我尝试连接到 143 ssl 服务器时，它说是普通连接。有什么办法可以像这样连接到商店吗？

java中除了javamail还有其他IMAP吗？

下面是一些代码->

Properties props = System.getProperties();
String imapProtocol = server.getImapSsl() != null && server.getImapSsl() == true ? "imaps" : "imap";
props.put("mail.store.protocol", imapProtocol);
props.put("mail." + imapProtocol + ".port", server.getImapPort());
props.put("mail." + imapProtocol + ".host", server.getImapHost());

javax.mail.Session mailSession = javax.mail.Session.getInstance(props, null);
Store store = mailSession.getStore();
store.connect(server.getImapHost(), server.getImapPort(), username, password);

更新(调试)->

DEBUG IMAP: enable STARTTLS
DEBUG IMAP: closeFoldersOnStoreFailure
DEBUG IMAP: trying to connect to host "imap.itheme.mn", port 143, isSSL false

你得到的端口号是倒过来的。 143 是纯文本。
