We are using AWS SES account in our FileMaker application to send mails. We using no-reply@domain.com account for sending the mails and it was working previously. But suddenly it stopped working and now we can not send the mail using no-reply with AWS account. Note: We have verified the no-reply@domain account by AWS SES. Please provide some details ASAP. Because this is the production issue and cant send mails from our app.
