Problems solved by technology
However, this can lead to abuse by some tenants of the cloud computing platform, such as sending unwanted or malicious emails from the platform
Unwanted email wastes machine resources, such as inbox storage
Unwanted email can be a vector for computer viruses to enter a computer, thereby posing a security threat to computing devices

The techniques described herein help improve email security within a multi-tenant email service. In particular, the techniques described herein help make a first tenant of the email service more difficult to pretenant a second tenant of the email service by verifying the transmit domain prior to the email leaving the multi-tenant email service. In particular, the techniques run sending-side source verification on the email. If the source verification fails, the email still will be sent, but the source IP address used will cause the email not to pass a recipient-side email authentication test, such as a sender policy framework (SPF) email authentication test. In contrast, if the source verification is passed, the email is sent using a source IP address that will cause the email to pass the recipient-side email authentication test.
Description
Background technique [0001] Cloud computing platforms may provide users with the ability to build, deploy, and manage services and applications in a distributed computing environment (ie, the cloud). When the cloud computing platform is provided by a cloud service provider, the tenants of the cloud computing platform do not need to provide or maintain their own infrastructure, thereby allowing the tenants of the cloud computing platform to rapidly deploy services and applications. Some resources of the cloud computing platform can be shared by tenants. For example, tenants in a multi-tenant email infrastructure can share IP addresses because the same server provides services to multiple tenants. However, this can lead to some tenant abuse of the cloud computing platform, such as sending unwanted or malicious emails from the platform. Unwanted email can waste machine resources, such as inbox storage. Unwanted email can be a vehicle for computer viruses to enter a computer, t...
