Question

这是我的代码。代码是groovy。

    //send email
    def host = "smtp.gmail.com"
    def props = new Properties()
    props.put "mail.smtps.auth", "true"
    def session = Session.getDefaultInstance(props, null)
    def msg = new MimeMessage(session)
    msg.setSubject subject
    msg.setText messageText
    msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to, to))
    def transport = session.getTransport "smtps"
    transport.connect(host, username, password)
    transport.sendMessage(msg, msg.getAllRecipients())
    transport.close()

    //fetch emails
    def host = "imap.gmail.com"
    def port = "993"

    Properties props = new Properties()
    props.setProperty("mail.store.protocol", "imap")
    props.setProperty("mail.imap.host", host)
    props.setProperty("mail.imap.port", port)
    props.setProperty("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.setProperty("mail.imap.socketFactory.fallback", "false");

    def session = Session.getDefaultInstance(props, null)
    def store = session.getStore("imap")

    store.connect(host, username, password)

    def inbox = store.getFolder("INBOX")
    inbox.open(Folder.READ_ONLY)

    def messages = inbox.getMessages()

连接imap store时此代码失败。

javax.mail.MessagingException: * BYE Cannot connect to IMAP server

如果我跳过使用smtp发送电子邮件，则提取部分可以正常工作。发送和提取邮件都使用相同的Gmail帐户。我想会话或gmail限制可能会有一些问题。发送电子邮件也正常。

使用SMTP后，与gmail的IMAP连接错误
