Hi,
I have read your project and we can install and configure email services for your domain hosted in ec2 instance. Had done so many mail server setups and have strong knowledge in AWS. You can check our reviews and confirm it.
We are a team of individual server administrators having many years of experience in the field of Linux/Windows administration, Cloud Management Services etc.
Kindly accept our proposal and we can have a detailed discussion through chat. Hope to hear from you soon.
Regards,
