odoo_smtp can't reach external SMTP servers

[nqb]

Hello,

I suppose odoo_smtp is a SMTP relay used by odoo container to send emails.

If variable mailname is defined in inventory, docker-compose.yml file for prod instance contain a smtp container attached to one network email_proxy. But this network is an internal network and doesn't allow smtp container to reach external SMTP servers.

I suppose smtp container should be attached to two networks:

• email_proxy
• email_public

My bad, the endif was not in the correct position (I had an extra if in order to be able to allow to define networks as internal or external).
Fixed with 5645ea5

Indeed, the idea is to block non authorized external communication (with whitelists, therefore you need email container which is able to discuss on Internet).
You can have a look here:

Thank you for reporting !
