Good to know

  • The BCC values are set on every user but are not switched on for them.
  • Tags save as soon as you add them. All other options need View / Save Changes.

Common questions

Can the BCC address be outside my domain?

Each BCC address in the incoming box must belong to a domain that exists on the XgenPlus server. Otherwise the save is refused.
