时事通讯发送缓慢 - 发送到同一服务器的 2 封邮件之间存在延迟/每小时最多发送多少封电子邮件？
我必须制作一个时事通讯发送实用程序应用程序，它将从我们的中央数据库收集订阅者列表并发送时事通讯。 我考虑过如果我一次清除所有电子邮件，可能会因洪水而被列入黑名单，因此我决定使用基于桌面的软件，该软件会缓慢地发送电子邮件。
我的问题是
- 每小时可以发送到同一电子邮件域（收件人/传入服务器）的最大电子邮件数是多少？
- 或者发送到同一服务器的两封电子邮件之间的延迟应该是多少，因为它不认为它是泛滥的？
以上哪一项更适合实际的邮件服务器配置...
谢谢
I have to make a newsletter sending utility application which will collect the list of subscriber from our central database and send out the newsletter. I've considered the possibility to be blacklisted due to flooding if I just flush out all emails at once, so I decided to go on a desktop-based softwer which will email those slowly.
my question is
- what is the max emails per hour that may be addressed to the same email domain (recipient/incoming server)?
- or what should be delay between 2 e-mails to the same server for it doesn't consider it flooding?
whichever of the above applies more appropriate to the real-world of mail servers configuration...
thanks

它确实会因配置而异，因此不一定有一个放之四海而皆准的答案。 您可能需要咨询您的 ISP - 您可能需要担心的是他们或他们的上游。
由于您要发送新闻通讯，您可以通过密件抄送而不是单个邮件添加多个收件人吗？ 这对所有相关人员来说应该不那么“辱骂”。
It's really going to vary by configuration, so there's not necessarily a one-size-fits-all answer. You might want to check with your ISP - it's probably them or their upstream that you'd need to worry about.
Since you're sending a newsletter, could you add multiple recipients via BCC rather than individual messages? That should be less "abusive" to all concerned.
我已实现每个收件人域最多发送 600 封电子邮件。 这似乎已经运行了一段时间了，听起来是一个不错的解决方案。
尽管如此，如果系统管理员对此有一些见解，我们将不胜感激。
I've implementing sending to max 600 e-mails per recipient domain. That seems to be working fine for some time now and sounds like an OK solution.
Still, some SysAdmin insight on this would be appreciated.
我每 2 封邮件后都会进行 Thread.Sleep(2000)
I make Thread.Sleep(2000) after every 2 mail
