问题：Google 将来自我的 apache/postfix 服务器的看似正确格式的电子邮件标记为垃圾邮件。电子邮件示例如下；
（我已将我的域替换为 mydomain.com.au，并将 IP 替换为假 IP）

how did you hear about us: Newspaper
- 我尝试将其发送到非谷歌电子邮件，并且它们可以正常到达。
- 我曾尝试发布到几个不同的谷歌账户，最终都成为垃圾邮件。
- Mydomain.com.au 使用 Google Apps 作为电子邮件提供商。
- 我在我的 NS 中添加了“v=spf1 a mx ~all”作为 TXT。
- 我使用http://remote.12dt.com/来检查反向 DNS，并且 IP 似乎可以很好地解析回域名。
标题看起来不错，并且 SPF 查找似乎通过了（？）..有什么想法吗？
亲切的问候
