I cannot set up external mail address under the "Mail to non-existng users" , the following error is shown:
Error: The specified email address 'firstname.lastname@example.org' is not valid. Since the Outgoing Mail Control Feature is on, the mail address must belong to the selected domain.
Due to the reason that Outgoing Mail Control cannot count messages sent to non-existing user, external email address for such users can be set up only by administrator.
