OPEN_DATA

OPEN_DATA is used to send the data command, informing the server that the email content is about to be sent. The email content is subsequently written using write_data and write_raw_data.

Syntax

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

UTL_SMTP.OPEN_DATA (
   c     IN OUT NOCOPY connection);

Parameters

Return values

Considerations

• OPEN_DATA, WRITE_DATA, WRITE_RAW_DATA, and CLOSE_DATA must be called in strict sequence. OPEN_DATA sends the data command to indicate the start of email content transmission. Multiple calls to WRITE_DATA and WRITE_RAW_DATA can then be made to send the email body, and finally, CLOSE_DATA sends the terminator to end the transmission.
• Must be called after RCPT.
• The expected response is a message starting with 250 or 251, indicating that the SMTP server has successfully responded and accepted the specified email content.
