Topic: Email service compared with mailgun or ses?
We have many businesses with even more domains that need to send email with dkim. Here is my issue, We are using a program that will be the go between to send out email from the individual sending domains. It acts as mailchimp and mailgun does in providing templates and outbound email and connects with all of our other services. Can IRedMail act as the smtp server so that the actual sending domain can send with dkim emails. We cant really individually add each domain or email address.
Explanation of our system
Multiple businesses each with multiple Sending domain with multiple email addresses
Our mailchimp like server program
Actual SMTP server that sends the email
How do I set this up or does someone have a guide? Any way to make this relay server, like get the transferred dkim from the sending domain.
