    Metadata

    EmailSender does not propagate metadata.

    EmailSender has no metadata templates.

    Metadata of the first output port are the same as those of the input port. However, metadata are not propagated from the input port to the first output port.

    Metadata of the second output port have the same fields as metadata of the input port plus one field named errorMessage. This field receives the information about the error that has occurred.

    EmailSender Attributes

    Attribute Req Description Possible values

    Basic

    SMTP server

    yes

    The name of an SMTP server for outgoing emails.

    e.g. smtp.example.com

    SMTP user

    The name of the user for an authenticated SMTP server.

    SMTP password

    A password of the user for an authenticated SMTP server.

    OAuth2 connection

    OAuth2 connection to authorize a connection to an authenticated SMTP server.

    Replaces SMTP password[1]

    Connection security

    Specifies the security protocol used to connect to the server.

    None (default) | STARTTLS | SSL

    Message

    yes

    A set of properties defining the message headers and body. For more information, see Email Message.

    Attachments

    A set of properties defining the message attachments. For more information, see Email Attachments.

    Advanced

    SMTP port

    The number of the port used for connection to an SMTP server.

    Integers

    Trust invalid SMTP server certificate

    By default, invalid SMTP server certificates are not accepted. If set to true, an invalid SMTP server certificate (with different name, expired, etc) is accepted.

    false (default) | true

    Ignore send fail

    By default, when an email is not successfully sent, the graph fails.

    If set to true, the graph execution continues even if no mail can be sent successfully.

    false (default) | true

    Connect timeout

    Timeout for establishing connection to the SMTP server.

    The value is in milliseconds. Additionally you can use other time units to define the time interval, e.g. 30s for seconds, 10m for minutes.

    5 minutes (default) | 0 (no timeout) | number of milliseconds or time interval

    Read timeout

    Timeout for reading from the SMTP server.

    The value is in milliseconds. Additionally you can use other time units to define the time interval, e.g. 30s for seconds, 10m for minutes.

    5 minutes (default) | 0 (no timeout) | number of milliseconds or time interval

    Write timeout

    Timeout for writing to the SMTP server.

    The value is in milliseconds. Additionally you can use other time units to define the time interval, e.g. 30s for seconds, 10m for minutes.

    5 minutes (default) | 0 (no timeout) | number of milliseconds or time interval

    Additional JavaMail Properties

    The component uses JavaMail library to send emails. This attribute can be used to specify additional configuration properties of JavaMail library to tweak its behavior, performance etc. See online documentation for properties relevant for SMTP. Note that if you set Connection security to "SSL", you need to use mail.smtps.* prefix instead of mail.smtp.*.

    Use short-lived connections

    By default, SMTP connection remains open for the entire time the component is running, which can be a very long time. The SMTP connection is kept open even if none or just few emails are sent.

    If you want to shorten SMTP connection lifetime, set this parameter to true. SMTP connection will be opened lazily (only when input data record is received) and closed immediately when no more data records are available on input edge.

    false (default) | true

    1

    Using OAuth2 connection to connec to Microsoft Exchange via SMTP requires SMTP.Send Scope to be specified.

    Email Message

    Email Attachments

    JavaMail System Properties

    EmailSender converts data records into emails. It can use input data to create the email sender and addressee, email subject, message body, and attachment(s). If no input edge is connected, this component sends one email.

    If a record is rejected and an email is not sent, an error message is created and sent to the errorMessage field of metadata on the output 1 (if it contains such a field).

    Email Message

    To define the Message attribute, you can use the following wizard:

    emailsendWizard
    Figure 360. EmailSender Message Wizard

    In this wizard, you specify a content of particular parts of an email message: drag and drop the proper field from the Fields pane to the Value column.

    You can also specify values to be used if the mapped field is empty. The alternative values of these attributes should be typed to the Alternative column. If a field is empty or has null value, Alternative is used instead of the field value.

    You can add additional headers using the plus button. This way, you set up Cc or Bcc.

    The resulting value of the Message attribute will look like this:

    From=$From|my@mail.com Subject=$Subject|mySubject To=$To|toWhom MessageBody=$Message|myText

    To send an email to multiple recipients, separate their addresses by a comma ','. If needed, use the same delimiter in the Cc and Bcc fields.

    Each field in the Properties table can be used as a template. Variable names are substituted with values from record.

    For example, the MessageBody field contains Hello, my name is $name. and the name field in input record contains the value Bob. The output message will contain the text Hello, my name is Bob.

    Email Attachments

    The Attachments attribute lets you add files as an email attachment.

    The attachment can be a file with invariable path (static file), a file whose name is received from an edge or a file whose content is received from an edge. These ways can be arbitrarily combined.

    The attachment is specified as a sequence of individual attachments separated by a semicolon. It is defined as a field name (file name received from an edge), as a file name including its path or as a triplet of field name, file name of the attachment and its mime type. Each of these three parts of the triplet can be also specified using a static expression.

    The attachments is added to the email using the following Edit attachments wizard:

    AttachmentsEdit
    Figure 361. Edit Attachments Wizard

    You add the items by clicking the Plus sign button and remove by clicking the Minus sign button. Input fields can be dragged to the Attachment column of the Attachments pane or the Arrow button can be used.

    If you want to edit any attachment definition, click the corresponding row in the Attachment column and the following attribute will open:

    Attachment
    Figure 362. Attachment Wizard

    In this wizard, you need to locate files, specify them using field names or the mentioned triplet. After clicking OK, the attachment is defined.

    If you want to use non-ASCII characters in filenames of attachments, value of the system propertymail.mime.encodefilename needs to be set to true. Any non-ASCII characters in the filenames will be encoded then (default is false).

    Default MIME charset to use for encoded words and text parts that don’t otherwise specify a charset (not only filename, but subject, message body as well) can be specified using the mail.mime.charset system property. The default value is the value of the file.encoding system property.

    JavaMail System Properties

    The EmailSender component is implemented using the JavaMail reference implementation library. JavaMail specification lists Java system properties which control behavior of the JavaMail implementation. For description of these properties, see the JavaMail API documentation. Use -D Java VM parameter to set the value of a system property.

    Notes and Limitations

    Metadata of EmailSender can have list and map fields. The map and list fields can be passed through, but they are not suitable for use in the component.
