我正在尝试在 groovy 脚本中使用 javamail 通过 gmail 发送电子邮件。我在网上看了很多地方,但到目前为止一直无法正常工作。运行脚本时出现的错误是:
DEBUG SMTP: useEhlo true, useAuth false
DEBUG SMTP: trying to connect to host "smtp.gmail.com", port 25, isSSL false
Caught: javax.mail.SendFailedException: Send failure (javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 25 (javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?))
尽管我已经指定它应该使用端口 587,但它似乎正在尝试使用端口 25。有谁知道可能导致此问题的原因,我使用 telnet 连接到端口 587 上的 smtp 服务器,而雷鸟使用具有 STARTTLS 安全性的端口 587,并且能够使用 smtp 服务器成功发送邮件。这告诉我这不是阻塞的端口或连接问题。这是我用来尝试发送电子邮件的代码:
import javax.mail.*
import javax.mail.internet.*
private class SMTPAuthenticator extends Authenticator
{
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication('email@gmail.com', 'password');
}
}
def d_email = "email@gmail.com",
d_password = "password",
d_host = "smtp.gmail.com",
d_port = "587", //465,587
m_to = "email@gmail.com",
m_subject = "Testing",
m_text = "This is a test."
def props = new Properties()
props.put("mail.smtp.user", d_email)
props.put("mail.smtp.host", d_host)
props.put("mail.smtp.port", d_port)
props.put("mail.smtp.starttls.enable","true")
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true")
props.put("mail.smtp.socketFactory.port", d_port)
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory")
props.put("mail.smtp.socketFactory.fallback", "false")
def auth = new SMTPAuthenticator()
def session = Session.getInstance(props, auth)
session.setDebug(true);
def msg = new MimeMessage(session)
msg.setText(m_text)
msg.setSubject(m_subject)
msg.setFrom(new InternetAddress(d_email))
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to))
Transport.send(msg)
任何帮助将不胜感激。提前致谢!
