Hi all of you,
I run 2012k trial version 180 day and after set up Mail I get this message after viewing history and doing the usual test...
mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 1 (2015-12-09T19:08:02). Exception Message: Cannot send mails to mail server. (El servidor SMTP requiere una conexión segura o el cliente no se autenticó. La respuesta del servidor fue: 5.5.1 Authentication Required. Learn more at).
Thanks for any input or hint,
