-B<fripost-adduser> adds a new mailbox to the system, unless B<--pretend>

+B<fripost-adduser> adds a new virtual mailbox to the system, unless
+B<--pretend> is set.
 If no I<username> or I<password> are given, the user is prompted for them.
 If I<username> is not fully qualified, C<fripost.org> is appended.
+If I<username> is already an existing username or alias,
+B<fripost-adduser> raises an error.
