With Outbound Email Filtering, you'll be able to manage:

Outbound policies

To modify your default Outbound policy, log into HostPilotĀ® Control Panel > Services > Email Protection > Outbound policies > Default policy. You can also create additional policies and set the priority for them. If multiple policies apply to a mailbox, the policy with the highest priority will be applied.

The default outbound policy cannot be removed. Outbound policies can be assigned to domains, Distribution Lists, mailboxes, Resource Mailboxes but not to Public Folders.

Spam settings

To define spam settings, navigate to Email Protection > Outbound policies > select the policy > Spam. There are three actions that can be used against Certain spam and Probable spam:

  1. Permanently delete
  2. Move to Admin quarantine
  3. Deliver to recipient

Read more about Outbound Quarantine Management in HostPilotĀ® Control Panel for more information.

Content filters

To add or remove contact filters, navigate to Email Protection > Outbound policies > select the policy > Content filters.

There are some predefined filters such as Credit Cards Number and Social Security Number which can be enabled. If multiple filters are applied to one policy, all actions associated with them will be employed. E.g. if a message matches both Credit Cards Number and Social Security Number filters which trigger Deliver to recipient and Move to Admin quarantine actions, the message will be sent both to the recipient and Admin quarantine.

Blocked and Safe recipients

To restrict users to email particular recipients, navigate to HostPilot > Services > Email Protection > Outbound policies > select the policy > Blocked Senders. To allow specific recipients to be emailed by your company, select Safe Senders tab.

You can add an email address and a domain name to the policy level Safe and Blocked recipients List. You will see a notification sign if the same sender is added to both Blocked Senders and Safe Senders lists simultaneously.

To import Safe Senders or Blocked Senders lists from CSV file, click Upload from CSV link.
Entries in the CSV files should be separated by commas or semi-colons or they should be on different rows.

Note: virus checks are always performed even if a sender is whitelisted.

Attachments

To manage or view attachment settings, navigate to HostPilot > Services > Email Protection > Outbound policies > select the policy > Attachments. You can select one action to apply to a message containing a dangerous attachment: either Drop it or Move to Admin quarantine.

To modify the list of attachments which are classified as dangerous, select a checkbox next to the file type and save changes.

You can specify file types which should be considered as dangerous even if their file type group is NOT selected in Dangerous attachments section.
Note: press space bar after you entered file type to finish editing.
For example, MS PowerPoint group is not selected, but if we add .ppt file type, it will be blocked, though other MS PowerPoint file types such as .pps, .ppsx etc. won't be blocked.

You can specify file types which should be considered as safe even if their file type group IS selected in Dangerous attachments section.
Note: press space bar after you entered file type to finish editing. 
For example, Executables group is selected, but if we add .reg file type here, it won't be blocked, though other executable files such as .exe, .scr etc. will be blocked.

Notifications to senders

To let the senders know that their message was rejected by Outbound filter, you can enable notifications via the Notifications tab.

 

The notification will be sent if one of the following conditions are matched:

  • a message was considered as spam
  • a message contained dangerous attachments
  • a message had 'not safe' content
  • a message was sent to a blocked recipient
  • a message contained a virus

Domain Key Identified Mail

This authentication technology allows senders to “sign” a message to prove it really did come from them. Once DKIM signing has been enabled for a domain, all outbound email messages from that domain will be signed using the current DKIM key.
