Odoo documenation describes setting up emails using a custom domain with Odoo’s email server and external email servers. According to the documentation, when Using odoo.sh or odoo online, the preferred method is using a custom domain with Odoo’s email server because it's easier to setup (?)
Well to me, it seems to be much easier to setup an external email server because i don't have to configure the SPF/DKIM/DMARC at the email host. I also don't have to rely on odoo's email servers.
Can someone please motivate why i should setup a custom domain with Odoo’s email server rather than an external email server which is super easy to setup?
I think i get it. You use odoo's email server with a custom domain if you only have a domain but not an actual email host server. If you do have the complete package, email host and domain, i guess it's better to use the email hosts smpt server (external email server).
It this right?
