Hi Support Team,
we just faced the following issue,

```

Could you please take care of this, or please advise how to fix this issue ASAP?
Thanks in advanced.

Answer

For immediate support, you should [create a support case](https://docs.aws.amazon.com/awssupport/latest/user/case-management.html#creating-a-support-case).

The [FAQs](https://docs.aws.amazon.com/ses/latest/dg/faqs-dnsbls.html#bl-q5) in the developer guide have a few recommendations. You could try contacting the postmaster of the domain that rejected your message.

If that is not feasible, you should consider using a dedicated IP address. The address is dedicated to you and allows you to control the reputation of that address.
