Re: I need replace source SMTP domain for all outgoing mail. how? Depends on versions, but usually, create an SMTP resource. Give it a name and color, skip all else and also check log at the bottom. Go to the "Action1" tab and in the sender fields use: *@domain.com ---> &@newdomain.com That should be it. Now in the outbound mail rule, delete SMTP, then right-click service field, select "Add with resource", choose SMTP and the newly created resource. Install policy and that should work. PS To create resources, go "Manage->Resources" |
