Hi, I have the same problem and I'm looking for someone who can help me do it step by step. The technical jargon is quite confusing. 

Hello, currently you have two main options:

- Opt for a third-party email service like Google Workspace to create mailboxes at mywebsiteDOTcom. To do this, you will need to link your domain to the email service by creating specific DNS records, usually MX and TXT records. You can create the required records on the Odoo.com portal.

Once the mailboxes are created, you can connect them as outgoing and/or incoming email servers in Odoo. For incoming emails, you can also use email forwarding to the default odoo.com aliases.

- The other option is to create a subdomain mailDOTmywebsiteDOTcom that you use as the email alias domain for the database. This allows you to create and update records in Odoo from emails received on your aliases at mailDOTmywebsiteDOTcom. The advantage of this option over the first one is that it does not require creating an account or purchasing a subscription with a third-party email service. You just need to create a CNAME record for mailDOTmywebsiteDOTcom with the value dbnameDOTodooDOTcom.
