我在本地试过163,126,sina的SMTP，都报Could not connect to SMTP host,java.net.SocketException: Permission denied: connect,我记得以前用同样的代码发送成功过的。不知道现在为什么不可以
代码：spring配置文件
<bean id="freeMarkerConfigurer"
class="org.springframework.ui.freemarker.FreeMarkerConfigurationFactoryBean">
<property name="templateLoaderPath" value="/WEB-INF/ftl/emailTemplate/" />

JAVA 代码：
public void sendEmail(String userName, String title, String content,
String address, String tempName) {
super.subject = title;
MimeMessage msg = sender.createMimeMessage();
MimeMessageHelper helper;
try {
helper = new MimeMessageHelper(msg, true, "utf-8");
helper.setTo(address); // 邮件接收地址
try {
helper.setFrom(new InternetAddress(getFrom(), "test"));
} catch (UnsupportedEncodingException e) {
log.error("sendEmail", e);
e.printStackTrace();
}
helper.setSubject(title); // 主题
String htmlText = getMailText(userName, address, content, tempName); // 使用模板生成html邮件内容
helper.setText(htmlText, true);
sender.send(msg); // 发送邮件
} catch (MessagingException e) {
log.error("sendEmail", e);
e.printStackTrace();
}
}
telnet smtp时提示：
220 irxd5-203.sinamail.sina.com.cn ESMTP
错误如下：
