So i have been trying to figure this out for days.

I'm fairly new to Odoo but i do not seem to understand the right system parameters to have the following mailsetup :

incoming mails : catchall@domain.com (already installed and working). --> mails are coming in and distributed over the aliases that i installed. And it seems to work.

Outgoing mails : Big problem! I always get the error that user-alias@domain.com is not the same as the sender postmaster-odoo@domain.com. 

I did delete the catchall.alias and the bounce.alias because it was recommended to do so. But i do not seem to be able to get Rob@domain.com send from info@domain.com unless its a personal reply or some kind of setup like that.

Error when sending an automated mail /template :
