Email Server Setup for Bulk Emails

I need assistance with setting up an email server capable of sending bulk emails efficiently and securely. The server needs proper configuration with email authentication protocols such as SPF, DKIM, and DMARC to ensure deliverability and safeguard against spam issues. While no specific platform or email-sending service has been chosen, the end goal is a fully functional bulk email setup tailored to professional needs. Please bring your expertise in server setup and email authentication protocols to the table.
