I have several smartermail servers using V11. In domain admin account, when I check the "Disable X-Originating-IP header in messages" setting in
Advanced Settings >> Default User Settings >> Compose
The setting does not save. I tried others like "Warn about common email mistakes prior to sending" and "Automatically check spelling prior to sending", there's no problem. It happens in all my servers.
I also found that in the System Admin account, I am able to save "Disable X-Originating-IP header in messages" for the User Default setting, however, when creating a new domain or user create an email account, this setting is unchecked.
Is this a bug?
