我无法使用Postfix将邮件发送到Gmail地址

我试图使用Postfix（默认的Debian设置）将邮件发送到我的测试GMail帐户，但失败了（“ /var/log/mail.log ”）：

Gmail认为这可能是垃圾邮件，因此无法传递。这是特定的消息：

<tshepang.test@gmail.com>: host gmail-smtp-in.l.google.com[209.85.229.26] said:
    550 5.7.1 smtp-proxy1.wa.co.za Message marked as SPAM, denied [7.600000]
    (in reply to end of DATA command)

请注意internet site，尽管Gmail将邮件放入了Spam文件夹（“ / var / log / exim4 / mainlog ”），但exim4可以工作（使用debconf设置，但其他所有设置均保留为默认设置）：

2011-09-26 16:20:24 1R8C2i-0000cr-QV <= wena@sugarmailer H=localhost ([127.0.1.1]) [127.0.0.1] P=esmtp S=370

2011-09-26 16:20:26 1R8C2j-0000ct-H4 Completed

另一个要注意的是，本地交付没有问题。

因此，问题是，在Postim失败时，Exim4中的什么使它能够通过Gmail服务器。
