Hello,

When Odoo is sending mails it uses the standard Odoo logo, but only when mails are opened locally. When opened externally the image is broken.
Which is logical since we're hosting on a local environment. This local environment is shut off for access from incoming traffic for security reasons.
web.base.url is set to the local IP (192.168.178.17) address. Company logo is correctly set.

I rather hard code the correct logo in the header instead of having a link to a local IP address which isn't accessible from the outside world.
Any tips on how to proceed in this particular case?
