How can I send a email in my Livecycle workflow without any attachment. I saw two component: "Email->Send with Document" and "SendEmailService>send" but I'm not able to send a email with my SMTP configuration and without attachment.
I use the email send with Document service and simply do not add an attachment. There is a global configuration in the adminui under Services/Applications and Services/Service Management and pick the SendEmail Service. Once that is configured you should be good to go.
