Dear Odoo-Community,

we have the following set-up:

* Odoo v14 Enterprise hosted on Odoo.sh - let's say the database-url is company.odoo.com

* We have our own domain - let's say it is company.com

* As mail_catchall_domain (set in system-settings), we've configured "company.com"

* For sending e-mails, we use the mail-server provided with odoo.sh

* In our DNS-settings, we've configured spf and dkim entries as suggested by the odoo-documentation

* We use Office365 as our mail-provider for any e-mails not exiting from odoo.sh

* In Office 365, we've configured a forwarding-adress, forwarding mails from  catchall@company.com to catchall@company.odoo.com

We now do the folowing steps:

* User A (with e-mail a@company.com) creates a SO for Client X (with e-mail x@client.com) and sends the offer via E-Mail through Odoo

* Client X receives the offer and replies to that e-mail, the reply will be sent to catchall@company.com => which will be forwarded to catchall@company.odoo.com

* Odoo sends a notification to User A but this notification is placed as Junk-Email

We were able to figure out that Odoo uses SRS for E-Mail forwarding - however, we are not sure what we did wrong during configuration.

Any help would be appreciated!
