Q: Is ESET Mail Security 4 for Microsoft Exchange Server compatible with Intelligent Message Filter?
A: Yes, ESET Mail Security 4 for Microsoft Exchange Server (EMSX) is compatible with Intelligent Message Filter
(IMF). The processing of emails in the case that message is evaluated as spam is as follows:
- If ESET Mail Security Antispam has the Delete message (or Quarantine message) option enabled the action
will be executed regardless of the action set in Microsoft Exchange IMF.
- If ESET Mail Security Antispam has the No action set, the Microsoft Exchange IMF settings will be used and
the relevant action executed (e.g. Delete, Reject, Archive...). Write spam confidence level (SCL) to scanned
messages based on spam score option (in Server protection > Microsoft Exchange Server > Transport
agent) must be enabled in order for this feature to work effectively.
Q: How do I setup ESET Mail Security to move unsolicited emails into the user-defined Microsoft Outlook spam
folder?
A: ESET Mail Security default settings cause Microsoft Outlook to store unwanted email in the Junk E-mail folder.
To enable this functionality select the Write spam score to the header of scanned email option (under F5 >
Server protection > Antispam protection > Microsoft Exchange Server > Transport agent). If you want the
unwanted email to be stored in a different folder, please read the following instructions:
1) In ESET Mail Security:
- disable the Write spam score to the header of scanned email option,
- enable the No action action for messages marked as spam,
- define a text tag that will be added into unwanted messages, e.g. "[SPAM]" (under Server protection >
Antispam protection > Alerts and notifications).
2) In Microsoft Outlook:
- setup a rule to ensure messages with a specific text in the subject ("[SPAM]") will be moved into the
defined folder.
Q: In the antispam protection statistics many messages fall into the Not scanned category. What email is not
scanned by the antispam protection?
A: The Not scanned category comprises of:
General:
All messages that were scanned while the antispam protection has been disabled on any layers (mailserver,
transport agent).
Microsoft Exchange Server 2003:
All messages incoming from an IP address, that is in the IMF on the Global Accept List
Messages from authenticated senders
Microsoft Exchange Server 2007:
All messages sent within the organization (all will be scanned by antivirus protection )
Messages from authenticated senders
Messages from users configured to bypass antispam
All messages sent into the mailbox, that has the AntispamBypass option enabled.
All messages from senders on the Safe Senders list.
NOTE: Addresses defined in the whitelist and antispam engine settings do not fall into the Not scanned category,
as this group is comprised solely of messages that were never processed by antispam.
