Symantec Email proxy rejection (intermittent) 1003,10
Would anyone know what my might cause this error to occur in MS Outlook (we are not running exchange, we use an external POP mail server with our ISP). Not all users are getting this and the one who is getting it is not getting the message on every EMail. But they are all running Symantec Endpoint Protection version 12.1.671.4971 as unmanaged clients. There message box is attached.
Also, if this is the wrong community can someone tell me where I should try posting this inquiry?
