scanned messages based on spam score – SCL is a
normalized value assigned to a message that indicates
the likelihood of the message being spam (based on the
characteristics of the message header, its subject,
content, etc.). A rating of 0 indicates that the message is
highly unlikely to be spam, while a rating of 9 indicates
that the message is very likely spam. SCL values can be
processed further by the Microsoft Exchange Server's
Intelligent Message Filter (or Content Filter Agent). For
additional information please refer to the Microsoft
Exchange Server documentation.
The When deleting messages, send SMTP reject
response option:
If unchecked, the server sends an OK SMTP response to
the sender's Mail Transfer Agent (MTA) in the format
'250 2.5.0 – Requested mail action okay, completed'
and then performs a silent drop.
If checked, an SMTP reject response is sent back to the
sender's MTA. You can type a response message in the
following format:
Primary
Compleme

Warning: Incorrect syntax of the SMTP response codes
can lead to malfunctioning of program components and
decrease effectiveness.

configuring SMTP Reject Responses.

Alerts and notifications
ESET Mail Security allows you to append text to the
original subject or body of infected messages.
By enabling Add to the subject of infected messages,
ESET Mail Security will append a notification tag to the
email subject with the value defined in the Template
added to the subject of infected messages text field (by
default [virus %VIRUSNAME%]). The above-mentioned
modifications can automate infected-email filtering by
filtering email with a specific subject (if supported in your
email client) to a separate folder.
NOTE: You can also use system variables when adding a
template to the message subject.
