OPEN_DATA

The OPEN_DATA procedure is used to send the data command to the server, indicating the start of sending email content. Subsequently, the email content can be written using the WRITE_DATA and WRITE_RAW_DATA procedures.

Syntax

UTL_SMTP.OPEN_DATA (
   c     IN OUT NOCOPY connection)
RETURN reply;

UTL_SMTP.OPEN_DATA (
   c     IN OUT NOCOPY connection);

Parameters

Return value

Considerations

• OPEN_DATA, WRITE_DATA, WRITE_RAW_DATA, and CLOSE_DATA must be called in strict sequence. OPEN_DATA sends the data command to declare the start of sending email content. After that, multiple calls to WRITE_DATA and WRITE_RAW_DATA can be used to send the email body, and finally, CLOSE_DATA sends the terminator to end the sending.
• It must be called after RCPT.
• The expected return value is a response starting with 250 or 251, indicating that the SMTP server has successfully responded and accepted the specified email content.
