Selfhosted Docker - SMTP settings not applied

[kiroubel-girma]

I have a Docker installation (ONLYOFFICE DocSpace v 1.1.1).
I changed the SMTP settings to use an alternate email server.
The test email works correctly.
I verified that the "SMTP test message" is sent via the custom SMTP server I specified.

However every email sent (such as new invite, welcome message, recovery email, etc.) does not use the custom SMTP server.
Instead all emails come from the default email service (notify.onlyoffice.info)
