Hi all, in the last two days we have noticed that that the italian domain tim.it and alice.it bounces all the email from our account. We also have tried using a dedicated IP but the problem persist. Here the error we receive every time

{"notificationType":"Bounce","bounce":{"feedbackId":"0113018ae07b9841-85cd5ccf-7426-4d1e-bde2-5fcf5b07cb58-000000","bounceType":"Transient","bounceSubType":"General","bouncedRecipients":[{"emailAddress":"xxxxxxx@tim.it","action":"failed","status":"5.3.0","diagnosticCode":"smtp; 550 mail not accepted from blacklisted IP address [23.251.247.100]"}],"timestamp":"2023-09-29T10:28:30.000Z","remoteMtaIp":"34.141.161.132","reportingMTA":"dns; e246-9.smtp-out.eu-west-3.amazonses.com"},"mail":{"timestamp":"2023-09-29T10:28:29.527Z","source":"xxxxx@xxxxxx.xx","sourceArn":"arn:aws:ses:eu-west-3:xxxxxxxxxxxxxxxxxxxxx","sourceIp":"xxxxxxxxxx","callerIdentity":"root","sendingAccountId":"xxxxxxxxxxxxxxxxxxx","messageId":"0113018ae07b92d7-0c4bdedd-38da-4cf9-a480-8639e7242479-000000","destination":["xxxxxxxxxx@tim.it"],"headersTruncated":false,"headers":[{"name":"From","value":"xxxxxxxx@xxxxx.xx"},{"name":"To","value":"xxxxxxx@tim.it"},{"name":"Subject","value":"Prova AWS"},{"name":"MIME-Version","value":"1.0"},{"name":"Content-Type","value":"multipart/alternative; boundary="----=_Part_146504_123947408.1695983309531""}],"commonHeaders":{"from":["xxxxxx@xxxxxx.xx"],"to":["xxxxxxx@tim.it"],"subject":"Prova AWS"}}}

Hi,

You seem to have been blocked from the error message. If the dedicated IP doesn't work, it probably means that those domains have raised the bar in terms of what they accept.

The AWS official gives solid guidance on what to do to avoid bounces: https://docs.aws.amazon.com/ses/latest/dg/send-email-concepts-deliverability.html
