在我们的测试中，我们使用IMAP从gmail服务器读取电子邮件。问题实际上是在gmail.com中它看起来像这样：
val props = new Properties() {
setProperty("mail.store.protocol", "imaps")
}
val session = Session.getDefaultInstance(props, null)
val store = session.getStore()
try {
store.connect("imap.gmail.com", "ouremail", "ourpassword")
val inbox = store.getFolder("Inbox")
inbox.open(Folder.READ_ONLY)
val msgCount = inbox.getMessageCount
val latestMessages = inbox.getMessages(math.max(msgCount - 100, 1), msgCount)
val message = inbox.search(new RecipientTerm(Message.RecipientType.TO, new InternetAddress(recipient)), latestMessages)
.headOption
.map(_.getContent match {
case str: String => str
case is: InputStream => Source.fromInputStream(is).mkString
})
但是当我们通过imap收到这些电子邮件时，它会变成这样：

它打破了我们的考验。它有什么理由打破空间，我们如何解决它？
UPD 这是代码： （它在scala中，但我认为它对于java开发人员来说也是可读的，商店有类型IMAPSSLStore）
