I just use one domain, so how can I set SOGo to use just "username" instead of "username@domain.com"
This occurs for both the web login and setting up activesync on a device.

Looking at the SOGo documentation it says this should be possible.

I have changed this setting from YES to NO and restarted the entire server but it didn't do anything.
// Must login with full email address
    SOGoForceExternalLoginWithEmail = NO;

Is it possible to do this?

Thanks
