SES dedicated ip not seen in email server

The issue you're experiencing with your SES dedicated IP address not being seen by your email server could be related to a few factors.

First, it's important to confirm that you're actually using the dedicated IP address for sending. When you have a dedicated IP address (standard) in Amazon SES, you should be able to see the specific IP address values in the Dedicated IPs page of the SES console. These addresses are static and assigned specifically to your account.

However, even if you have a dedicated IP address, SES might still use shared IP addresses in certain situations, especially during the warm-up period. The warm-up process is crucial for building a good sending reputation for your new dedicated IP. During this time, SES gradually increases the volume of emails sent through your dedicated IP while still using shared IPs to ensure reliable delivery.

You mentioned that you've marked the warm-up exercise as complete. However, it's worth noting that simply marking it as complete doesn't immediately switch all traffic to your dedicated IP. The warm-up process typically takes about 45 days to complete fully.

If you're still not seeing your dedicated IP being used after marking the warm-up as complete, you should check a few things:

1. Ensure that you're specifying the correct configuration set associated with your dedicated IP when sending emails.
2. Verify that you're sending enough volume consistently to maintain the IP's reputation. If your sending volume drops significantly, SES might route some traffic through shared IPs to protect your dedicated IP's reputation.
3. Double-check that you haven't accidentally disabled the use of your dedicated IP in your SES settings.

If you've verified all these points and are still experiencing issues, it would be advisable to contact AWS Support for further assistance. They can provide more specific guidance based on your account's configuration and sending patterns.
