在网页上施加电子邮件限制
为了避免垃圾邮件发送者,在从我们的网站发送电子邮件时对用户施加限制的好策略是什么?单个 IP 每天的计数限制?发件人电子邮件?域名?一般来说,推荐的数字也会有帮助。
我们的用户可以通过我们的网页发送电子邮件。他们可以注册和登录,但也可以在不登录的情况下执行此操作,但需要使用验证码和发件人电子邮件字段。当然,有一个标题,“用户已向您发送了以下消息。”,限制了垃圾邮件发送者的使用,所以也许这不是一个大问题。
任何对我正在做的事情的评论将不胜感激。
To avoid spammers, what's a good strategy for imposing limits on users when sending email from our site? A count limit per day on individual IPs? Sender emails? Domains? In general terms, but recommended figures will also be helpful.
Our users can send emails through our web page. They can register and log in but are also allowed to do this without logging in, but with a captcha and with a field for the senders email. Certainly, there is a header, "The user has sent you the following message.", limiting the use for spammers, so perhaps it's not a big problem.
Any comments on what I'm doing will be greatly appreciated.

IP 地址,而不是发件人电子邮件;可以轻松旋转和伪造。
IP addresses, not sender emails; which can be easily rotated and faked.
