In Mailscan for SMTP 6.4a -> in the Webfrontend ->
at Position "Scan Control" -> "Do not Scan Mails" ->
clicking the "Add" Button to enter eMail addresses ->
results in an error message dialog "Invalid eMail Id Specified!"
This is for "FROM USER" as "TO USER"
In contrast this function works via the local Content Administrator dialog[/img]
