You can protect mailing and distribution lists from spam and viruses. These lists are addresses that deliver a message from outside your network to a group of people in your domain, such as partners@your_domain.com, or noon_cyclers@your_domain.com. Often, when users complain about spam passing through, they’re receiving the spam through their membership to a mailing list.
To protect a mailing list from spam and viruses, you must alias the mailing list to an existing or new user account.
WARNING: Do not add the mailing list as a user account. The mailing list is treated as a user, so all members of the mailing list, including those outside of your organization, will receive the notifications and quarantine summaries. You can turn off all notifications except the new password message. If you forget the password, the new password is sent to everyone on the mailing list.

Alias the mailing list to an existing user, such as an administrator or the designated owner of the mailing list.
|
Considerations: The mailing list receives the same settings as the user—spam filters, approved and blocked senders, etc.—which may or may not be appropriate for the mailing list.
|
|
Create a new user account for the mailing list and alias the mailing list address to this account. You can choose to send the notifications to the designated owner of mailing list.
|
Considerations: The advantage of this method is that you can specify the filter settings for the mailing list. However, this is another user account to manage,
The mailing list will receive the protections as the user. Only the registered user receives the notifications and quarantine summary.
Add a user that will represent the mailing list. For example, info_mailing_list@jumboinc.com. This user should not have an email account on your mail server. This user account serves only for filtering and not for mail traffic.
The user can be added to any user organization. The filter settings for the organization will apply to the mailing list, so this may help you choose the appropriate organization.
Select the mailing list user, and click Notifications. Add the list owner’s email address to the Notification address. This allows only the list’s owner to receive the quarantine summary, notifications, and password changes.
Select the mailing list user account, and configure Spam Filtering, and add any approved or blocked senders.
Your mail lists receive virus protection and spam protection. The users on the mailing list won’t be bothered with any notifications.
