You can use things like DKIM or SPF in your domain. It means you are stating that you 'authorize' mail via server X. These measures increase the 'reputation' of sending mail servers for your domain.
But the verification checks are made on the recipient. No one really blocks based on SPF or DKIM since email is 'open' in that sense that you can send a 'valid' email from anywhere.
It's up to to the receiving email server to determine if they want to accept and forward on a sending email.

简而言之，不。
通过开放 SMTP 中继发送的邮件可以显示为来自任何电子邮件地址。
In short, no.
Mail sent through an open SMTP relay can appear as being from any e-mail address.
您可以在域中使用 DKIM 或 SPF 等内容。这意味着您声明您通过服务器 X“授权”邮件。这些措施可提高您所在域的发送邮件服务器的“声誉”。
但验证检查是针对收件人进行的。没有人真正基于 SPF 或 DKIM 进行阻止，因为电子邮件是“开放”的，您可以从任何地方发送“有效”电子邮件。
由接收电子邮件服务器决定是否要接受并转发发送电子邮件。
