The filtering systems are fully configurable and allow you to effectively protect your email. This step is not necessary to start the service.
Indeed, the default setting provides you with an adequate level of protection and security.
However, the extensive functions for
configuring security rules at domain and/or user level, list management and
user subscriptions to their quarantine report, will allow you to fine-tune the
service to suit your specific email usage. The console reports and feedback
from your users will be excellent indicators for refining or customising this
setting over time.
Administrators can configure the security policy they wish to apply to messages in the protected domain, or to certain users (or groups of users). The configurations are put into production at regular intervals (10 min) on all processing servers.
Configuration of security rules :
The configurations can be applied
- At the level of the entire domain
- For a user or a group of users (see below)
For most of the configuration blocks, the possible actions :
- Quarantine: put in quarantine (users will then be able to release messages blocked in Quarantine, depending on their subscription)
- Destroy: Permanently delete the message making it impossible to recover. This is the behaviour applied when a virus is detected.
- Tagging: Add a "tag" between brackets at the beginning of the subject of the message: [SPAM], [NEWS] or other.
- Deliver: do nothing at the filtering level, and pass the message on as is.
In the Notification block, you can choose to notify :
- Sender: the sender of the message
- Recipient: the recipient of the message
- Administrator: the domain administrator (the one defined in "Domain Settings").
You can alert several people at the same
time (in this case you need to put a group/list email address).
If the action is "Deliver", no one will be warned, even if there is a checkbox. Depending on the threat, it is possible to refine the rules.
The configuration is used to set the filtering rules, which define what action to take and who to alert when a threat is intercepted.
For each rule, different parameters can be chosen:
Setting the spam meter thresholds
Humail check (turing test) by captcha
Permanent removal of viruses
Classification or categorisation of e-mails
Enable anti-spoofing (only for the domain rule)
Limit the maximum size of e-mails
Detection of content types to deliver, quarantine or delete the email
Detection of non-RFC SMTP compliant emails
Geographic filtering
