## Symptoms

- * Disclaimer "Email secured by Check Point" is not added for some SMTP traffic.
* email is scanned, scan log is generated.

## Cause

The root cause for this is the use of the BDAT command.

BDAT is an ESMTP command that replaces the SMTP DATA command.  
When BDAT is sent, the SMTP host will not have to continuously scan for the end of the data. This command sends an argument that contains the total number of bytes in a message.

The receiving server counts the bytes in the message. When the message size equals the value sent by the BDAT command, the server assumes it has received all of the message data.

**The use of BDAT will not allow to add the disclaimer.**

Example from debug - disclaimer added successfully:
===================================================

`AM_insert_disclaimer_into_segment:DEBUG: Inserting TEXT disclaimer ( Email secured by Check Point ) � mime_alter.c:2334:AM_insert_disclaimer_into_segment:DEBUG: Conditions right for HTML disclaimer to be added mime_alter.c:1464:AM_add_disclaimer_insert_html:DEBUG: Starting to attempt to insert HTML disclaimer`  
`================================================`  
emaild_disclaimer_add: A disclaimer was successfully added to the email.  
`================================================ `

Example from debug - with BDAT:
