java - apache james邮件服务器发送电子邮件

Question

您好，我正在使用 apache james 电子邮件服务器 2.3.2 通过我的 Java 应用程序发送电子邮件 我已经设置它并使用 JavaMail API 1.4。我正在尝试向 gmail/yahoo 等邮件服务器发送电子邮件。

我可以将邮件发送到本地主机上的帐户(本地运行 James 的帐户)，但不能发送到外部电子邮件服务器。

我也更改了/apps/config.xml。我在 James 上有我的 MyMailet 样本。 它没有抛出任何异常。 但 mailet*.log 是这样的:

13/06/12 15:20:13 INFO  James.Mailet: MyMailet#init called
13/06/12 15:20:13 INFO  James.Mailet: RemoteAddrNotInNetwork: Authorized addresses: [127.0.0.1/255.255.255.255]

dnsserver*.log 如下:

13/06/12 15:20:13 INFO  dnsserver: DNS Server is: 192.168.15.3

james*.log like:
13/06/12 15:20:13 INFO  James: JAMES init...

cofig.xml 如下:

    <processor name="transport">
        <mailet match="All" class="RemoteDelivery">
        <outgoing> file://var/mail/outgoing/ </outgoing>

            <gateway>192.168.15.186</gateway>//My IP addresss. Tried with smtp.gmail.com also
            <gatewayPort>25</gatewayPort>
            <gatewayusername>user123</gatewayusername>
        <gatewayPassword>pass123</gatewayPassword>

        <!-- Set the HELO/EHLO name to use when connectiong to remote SMTP-Server -->

        <mail.smtp.localhost>myMailServer</mail.smtp.localhost>

        </mailet>

  </processor>

Answer 1

我认为由此引起的问题:

电子邮件服务器在接受任何邮件之前都会执行反向 DNS 查询。他们检查电子邮件来自的域的 IP 以及电子邮件真正来自的 IP。

如果域的 IP 和电子邮件发件人的 IP 不匹配，邮件服务器会认为该电子邮件是垃圾邮件。

这里，因为当电子邮件服务器发送反向 DNS 查询未获取 IP 并认为您的邮件是垃圾邮件时，您的域(我不知道它是什么:-？)不是有效地址。
