Options

Mail

TO
Email address of the intended recipient
CC

Carbon Copy: Additional recipients who may also be interested in the message.

BCC

REPLY TO

Subject
The Subject of your message.
Body
The body of your message. Note that the list to the left of the text box allows you to reference flow variables in your message.
Priority
The X-Priority flag in the mail header. Standard email clients display the email in different styles depending on the flag.
Text/HTML
Choose whether your message should be interpreted as plain text or HTML. Note, if HTML is chosen you will have to enter HTML tags manually. This option is mostly useful when used in conjunction with flow variables, whereby a flow variable contributes the email text.

Attachments

File Chooser
Choose a file (or more than one) to attach to your email. To include temporary data from your KNIME workflow, consider using a Create Temp. Dir. node along with the relevant file writers to create your attachments. The trash icon will remove the selected file, and the up/down arrows will reorder the attachments in the final email.

SMTP Port

FROM

SMTP Host Authentication
Check this box if your SMTP host requires authentication.
Workflow Credentials
Enable workflow level credentials. These must be defined for the workflow in the KNIME Explorer by selecting "Workflow Credentials" from the context menu for an open workflow.
User Name / Password
Enter your user name and password if using simple authentication (as opposed to the Workflow Credentials described above).
Connection Security
