如何为征集的促销电子邮件提供 smtp 服务器?

发布于 2024-07-07 06:04:16 字数 135 浏览 5 评论 0原文

我有一位客户需要向他的联系人发送一些直接邮件,这些邮件是从贸易展览等收集的。我正在考虑为他们提供一个基于网络的解决方案来发送直接邮件材料 - 然而这种解决方案总是面临一个重大困难将服务器列入黑名单。 我想知道对于如何维护这样的SMTP服务器有什么建议吗?

I have a customer who needs to send some direct mailing to his contacts which is being collected from trade shows etc. I am thinking about providing a web based solution for them on sending direct mailing material- however this kind of solution always face a major difficulty on having the server blacklisted. I would like to know if there is any suggestions on how to maintain such SMTP server?

  • 让您的 SMTP 服务器使用您的特定 DNS 名称(而不是通用 IP 或通用反转)响应 HELO/EHLO 命令(是: mail.example.com ;否: 1.2.3.4 、 4-3-2-1.dsl.example.com )
  • 拥有与 HELO 响应匹配的反向 DNS(例如:nslookup mail.example.com -> 1.2.3.4、nslooup 1.2.3.4 -> mail.example.com)
  • 确保除了合法用户之外没有人可以发送电子邮件,禁止打开中继或转发器!
  • 正确发送必填电子邮件地址(滥用、邮件管理员和信息、IIRC),并且电子邮件的回复地址存在并定期检查(重复发送到死电子邮件地址可能会导致列入黑名单)
  • 检查双重选择加入用于互联网驱动的订阅
  • 还要确保退出功能有效
  • 有明确的免责声明

而且,以防万一:
- 确保 SMTP 的 IP 地址与其他 SMTP 不同,这样万一出现故障,您仍然可以从其他帐户发送邮件!

  • Have your SMTP server respond to HELO/EHLO commands with your specific DNS name, not generic IP nor generic reversal (YES: mail.example.com ; NO: 1.2.3.4 , 4-3-2-1.dsl.example.com )
  • Have a Reverse DNS matching the HELO response (example: nslookup mail.example.com -> 1.2.3.4, nslooup 1.2.3.4 -> mail.example.com)
  • Make sure nobody but legit users can send emails, no open relays or forwarders!
  • Have the mandatory email addresses correctly delivered (abuse, postmaster and info, IIRC), and that the reply-to address of the email exists and are regularly checked (repeatedly sending to dead email addresses can incur in blacklisting)
  • Check that double opt-in is in use for internet-driven subscriptions
  • Also make sure opt-out is working
  • Have a clear disclaimer

And, just in case:
- Make sure the IP address of the SMTP is different from your other SMTPs, so in case something fail you're still able to send mails from other accounts!

除了服务器(只需设置 exim 或 postfix 以及一个用于发送新闻通讯的 Web 界面,并在 IP 地址不同于您自己的个人邮件服务器(甚至可能是不同的网络)的服务器上执行此操作)之外,您还可以希望您的使用条款和条件良好且严格,以便您可以取消任何对电子邮件有投诉的客户对系统的访问权限。 事实上,您可以强制要求发送的所有电子邮件都必须合法(例如,有效的取消订阅选项等)。

Aside from the server (just set up exim or postfix and a web interface to send newsletters from, and do this on a server with an IP address that is different from your own personal mail server (maybe even a different network)), you will want to get your terms and conditions of use nice and tight so that you can remove access to the systems from any customer that has complaints made about emailing. Indeed you can mandate that all emails sent must be lawful (e.g., unsubscription option that works, etc).
