To add some additional information regarding what we are trying to achieve:
- An email server as a docker container. Prefer EXIM however Postfix would work - A POP3/IMAP server as a docker container The containers will be deployed to a kubernetes cluster on GCP. We also want DKIM and all the verification to work perfectly. This is for my own company, security is a must :) Can anyone please help guide in the right direction?
