尝试向电子邮件地址在 Microsoft 365 中的收件人发送电子邮件时是否收到错误消息?Are you getting an error message when you try to send an email to a recipient whose email address is in Microsoft 365? 如果您认为不应收到错误消息,您可以使用除名门户将自己从阻止的发件人名单中删除。If you think you should not be receiving the error message, you can use the delist portal to remove yourself from the blocked senders list.

阻止的发件人名单是什么?What is the blocked senders list?

Microsoft 使用阻止的发件人名单来防止其客户遭受垃圾邮件、欺诈和网络钓鱼网站的攻击。Microsoft uses the blocked senders list to protect its customers from spam, spoofing, and phishing attacks. 由于多种原因之一,您的邮件服务器的 IP 地址(即邮件服务器用来在 Internet 上标识自身的地址)被标记为对 Microsoft 365 的潜在威胁。Your mail server's IP address, that is, the address your mail server uses to identify itself on the Internet, was tagged as a potential threat to Microsoft 365 for one of a variety of reasons. 当 Microsoft 365 将 IP 地址添加到列表中时,它会阻止该 IP 地址与任何客户通过我们的数据中心进行进一步的通信。When Microsoft 365 adds the IP address to the list, it prevents all further communication between the IP address and any of our customers through our datacenters.

在您收到包含类似于以下错误的邮件回复时,您就知道自己已被添加到该列表中:You will know you have been added to the list when you receive a response to a mail message that includes an error that looks something like this:

550 5.7.606-649 访问被拒绝,已禁止发送 IP [IP 地址];若要请求从此列表删除,请访问 https://sender.office.com/ 并按照说明操作。550 5.7.606-649 Access denied, banned sending IP [IP address]; To request removal from this list please visit https://sender.office.com/ and follow the directions. 有关详细信息,请参阅Email non-delivery reports in Exchange Online。For more information see Email non-delivery reports in Exchange Online.

其中 IP address 是邮件服务器在其上运行的计算机的 IP 地址。where IP address is the IP address of the computer on which the mail server runs.
