sender score才16分:Infrastructure high
Infrastructure
All email senders have a responsibility to appropriately handle bounced email, complaints, etc. Leading senders will augment this with automated ISP feedback loop handling and other programs to actively manage their Sender Score and reputation. Senders who do not have an appropriate method for handling bounces and error codes, do not publish a postmaster, abuse email address or publish the necessary MX records will be considered as high risk and receive a lowered Sender Score.
