使用其他域的发件人地址发送SMTP
我的目标是在服务器上创建罐装电子邮件，然后从客户端电子邮件地址发送电子邮件。为此，我知道它必须来自与发件人地址匹配的域，而不是被标记为垃圾邮件。
我需要从中发送许多用户电子邮件地址，所有这些电子邮件地址都具有相同的域。在与客户的合作下，我是否可以将其设置为使用一个SMTP凭据，还是需要为每个用户使用凭据？
My goal is to create a canned email on my server and then send the email from client email addresses. To do this and not be marked as spam I understand it must come from a domain matching the from address. There are many user email addresses I would need to send email from, all with the same domain. With cooperation from my client, could I set this up to work with one SMTP credential or would I need credentials for each and every individual user?
为了澄清，如果我得到了一个来自我的客户端的带有un / pw的SMTP服务器地址，足以发送给以下地址：
To clarify, if I get an SMTP server address with a un/pw from my client, would that be enough to send from:
george@example.com
martha@example.com
ted@example.com
george@example.com martha@example.com ted@example.com
谢谢！

您要避免 joe-jobbing 在您的自动消息中。

You want to avoid joe-jobbing in your automated messages.
这取决于您如何向
- 如果您要为每封邮件向远程SMTP服务器进行身份验证，则需要为每个用户提供凭据。 >
- 如果您将邮件直接注入经过授权可发送域邮件的MTA中（例如，使用 sendmail 命令），则只需要特权访问权限。
- If you're authenticating to a remote SMTP server for each message, then you need credentials for each user.
- If you're injecting messages directly into an MTA (e.g. with the sendmail command) that is authorized to send mail for the domain, then you only need privileged access.
