I'm trying to get mass mailing working in Odoo. We can create mailing and can send them via SMTP configured in the outgoing email server configuration.

However; deliverability is severely impaired. Odoo uses a bounce email address on the fully qualified domain name; odoo.example.com. We don't have an email server on this subdomain, so there are no MX, SPF, DKIM, or DMARC records in the DNS. We can add an SPF record, but it's pointless when there are no MX records, and we can't create MX records for a non-existent mail server.

The only documentation I can find is applicable to hosted Odoo Enterprise. We are self hosted community edition.

Can anyone point me to documentation or suggest how this is all intended to work. I love Odoo, but it's often not clear how something works, and the documentation is just not sufficient.

As a supplementary question; how feasible is it to use a service such as Amazon's SES for mass mailings?
