java - 使用java发送邮件时出现异常

Question

我在春天使用一个应用程序，有一个与发送邮件有关的问题。发送邮件时发生异常

“javax.mail.MessagingException: 501 5.0.0 HELO 需要域地址”。

当我研究这个问题时，我们发现它与发送邮件的机器有关。

这就是我首先设置邮件属性的方式

<bean id="mailSession" class="javax.mail.Session" factory-method="getInstance">
        <constructor-arg>
            <props>
                <prop key="mail.smtp.auth">${mail.smtp.auth}</prop>
                <prop key="mail.smtp.socketFactory.port">${mail.port}</prop>
                <prop key="mail.smtp.socketFactory.class">${mail.smtp.socketFactory.class}</prop>
                <prop key="mail.smtp.socketFactory.fallback">${mail.smtp.socketFactory.fallback}</prop>
                </prop>
            </props>
        </constructor-arg>
        <constructor-arg ref="smtpAuthenticator" />
    </bean>
    <bean id="smtpAuthenticator" class="com.iris.allofactor.commons.mail.SmtpAuthenticator">
        <property name="logger"><ref bean="logger"/></property> 
        <constructor-arg><value>${mail.username}</value></constructor-arg>
        <constructor-arg><value>${mail.password}</value></constructor-arg>
    </bean>
    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host"><value>${mail.host}</value></property>
        <property name="session" ref="mailSession" />
    </bean> 

在获得 HELO 异常后，我添加了另一个权限

<prop key="mail.smtp.localhost">${mail.smtp.localhost}

${mail.smtp.socketFactory.fallback} 之后

现在没有异常邮件是成功的，但是我的收件人没有收到邮件。任何人都可以帮我解决这个问题

我在加载 bean 时也遇到异常，异常是这样的

我不认为这可能是核心问题，请帮助我找到解决方案

Answer 1

我遇到了类似的问题，您应该采取以下措施来解决问题。

当您的机器启动时，它需要知道一些主机名到 IP 地址的映射，然后才能引用 DNS。此映射保存在 /etc/hosts 文件中。在没有名称服务器的情况下，系统上的任何网络程序都会查询此文件以确定与主机名对应的 IP 地址。

似乎您正在应用程序中实现邮件内容，它试图首先找到本地 IP 映射以路由 TCP/UDP 包

做就是了 ：

1. vi /etc/hosts

2. 现在你可以看到

   27.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
   ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

3. 修改第一行并附加 Tomcat2 Tomcat2.localadminTomcat2，如下所示

27.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 Tomcat2 Tomcat2.localadminTomcat2
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

而已。

问候，艾米

Answer 2

来自 Oracle/Sun 官方网站，

问：我在尝试发送消息时收到“MessagingException: 501 HELO requires domain address”。答：SMTP 提供程序在 SMTP HELO 命令中使用 InetAddress.getLocalHost().getHostName() 的结果。如果该调用未能返回任何数据，则不会在 HELO 命令中发送名称。检查您的 JDK 和名称服务器配置以确保该调用返回正确的数据。您还可以将“mail.smtp.localhost”属性设置为您要用于 HELO 命令的名称。

来源：http ://www.oracle.com/technetwork/java/faq-135477.html#helo

据我了解，当您的电子邮件服务器查看由 InetAddress.getLocalHost().getHostName() 返回的 Java Web 服务器的名称然后拒绝它时，就会发生这种情况。如果电子邮件服务器无法对 Web 服务器进行反向 dns，或者如果 Web 服务器提供了无意义的名称（例如 localhost），则主机名可能会被拒绝。如果您的网络服务器将自己标识为 localhost，请尝试添加 JDK 属性，例如 props.put("mail.smtp.localhost", "real-hostname.com");

Answer 3

我今天收到了同样的错误信息。它无法解析“本地主机”。将您的 IP 地址和服务器名称简单地添加到主机文件 /etc/hosts 即可解决它。

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 Tomcat2: Tomcat2

yourIP      Tomcat2: Tomcat2 "your hostnamename"

Answer 4

c3po 池正在尝试使用InetAddress.getLocalHost().getAddress();. 如果无法解析本地主机地址，这将产生异常。很可能您的机器主机地址配置错误。请注意您的 Linux 服务器上的 /etc/hosts 应正确配置并对应 /etc/hostname。
