I'm using Odoo V13 on Odoo.sh.
We've been using Google's SMTP Relay service successfully with Odoo Online, but this stopped working the moment we moved over to Odoo.sh - does anyone either have a solution for this, or another recommended supplier that can send emails for us as an open relay from Odoo.sh?
Just as a side note - smtp.google.com works 100% all of the time on Odoo.sh, but smtp-relay.google.com works a small percentage of the time. When it doesn't work, Odoo reports: "Connection closed unexpectedly".
Regards,
Rayno
