E-mail spam filtering software for everyone who manages e-mail for multiple domains

CanIt-Domain-PRO is anti spam software designed for managed service providers, web hosts, ISPs, universities and anyone who has to provide e-mail spam protection for multiple domains. CanIt-Domain-PRO enables a super system administrator to delegate system administration rights which in turn allows the designated system administrator to offer per-user or per-group anti spam filtering.

CanIt-Domain-PRO Features:

  • Customizable and scalable spam and virus protection
  • Automatic updates in spam protection software
  • Inbound and outbound mail spam scanning
  • Per user Bayesian analysis including access to RPTN
  • Available as software or as an appliance
  • Built on top of CanIt-PRO, CanIt-Domain-PRO is designed for complex environments where global spam protection policies must be balanced with an individual's ability to have the final decision over what is and is not spam. CanItâ„¢ products offer the industry's most complete and flexible spam filters. They can be deployed in any enterprise e-mail environment.


    CanIt-Domain-PRO protects users from seeing other users' data, settings and incidents. A regular user will not be able to adjust, manage or otherwise interact with any settings or information on the system that does not relate to their account. Administrators of the system are granted access to manage these settings on the users' behalf.

    Creation or Deletion of Customers

    Only overall site administrators can create the initial domains and administrative accounts for those domains on the CanIt system. This provides you the ability to be the single point for customer creation.

    A CanIt-Domain-PRO site contains a number of realms, where each realm corresponds to one administrative entity. Typically each client will have its own realm. However, it is conceivable that a large organization might want separate realms for different departments. Or in the example where you have a reseller partner, each of the reseller's clients would be set up as a realm.

    A person in charge of a realm is called a realm administrator. A person in charge of the overall CanIt-Domain-PRO installation is called a site administrator.

    Creation or Deletion of Domains

    CanIt-Domain-PRO provides the ability for the site administrator to create new domains. Each domain is attached to a realm. A realm can have multiple administrator accounts which can be created either by an existing realm administrator or by the site administrator. CanIt can be configured so that each domain is has its own realm. This allows a single domain to have multiple administrators.

    Creation or Deletion of Subdomains

    Any realm administrator or site administrator can add additional subdomains to an existing realm. The subdomains can only be created if there is already a matching parent domain found in the realm being accessed by the administrator. This allows for the addition of a domain like xx.yy.zz to a realm that already contains yy.zz, but does not allow for the addition of a realm yy.xx.zz to this realm.

    Creation or Deletion of Users

    Any administrator (realm or site) may create user accounts within the realms that he or she administers. This allows the site administrator to manage all accounts and users on the system while still allowing other administrators to manage the users within their own realms.


    CanIt-Domain-PRO provides the ability for end users to manage their own settings and options. They can manage how mail is detected as spam, if it is to be automatically rejected (discarded), held in a trap or tagged and passed through. Users also can manage their own rules for whitelisting, blacklisting, content filtering, DNSBLs, Bayesian settings and so on. Administrators can set permissions to restrict the settings users have access to.

    In specific cases, other users can be granted access to manage another user's settings. This is done by explicitly indicating which accounts a user has access to manage. This is done by the administrator of the system.

    Email Aliases

    CanIt-Domain-PRO divides incoming email messages into streams. Multiple email addresses can be mapped to a single stream, which is administered by one user.

    The mapping of email addresses into streams can be done in a variety of ways, including via LDAP lookups, server-side scripts, or manual entries. If a user's email aliases are stored in LDAP, then CanIt will automatically map mail for any of those aliases into the user's stream.
