azure - 如何在 Azure 中设置 smtp 服务器

Question

可以在 Azure 中设置 Windows VM 来充当 smtp 服务器吗？我在某处读到它违反了 Azure 政策，是否有官方文档说明了这一点？

Answer 1

This doc提到过:

Starting on November 15, 2017, outbound email messages that are sentdirectly to external domains (such as outlook.com and gmail.com) froma virtual machine (VM) are made available only to certain subscriptiontypes in Microsoft Azure. Outbound SMTP connections that use TCP port25 were blocked. (Port 25 is primarily used for unauthenticated emaildelivery.)

Microsoft recommend you use authenticated SMTP relay services (thattypically connect through TCP port 587 or 443 but support other ports,too) to send email from Azure VMs or from Azure App Services. Theseservices are used to maintain IP or domain reputation to minimize thepossibility that third-party email providers will reject the message.Such SMTP relay services include but aren't limited to SendGrid. It'salso possible you have a secure SMTP relay service that's runningon-premises that you can use.

希望有帮助。
