Prefilter Used to typically invoke spam filtering with SpamAssassin. The prefilter gives access to the email mailpack prior to it being decoded by Xamime, this allows the administrator to examine and modify the mailpack in an untouched state.
External Within an ACL test, Xamime can call on an external program to perform various tasks applied to the unpacked email.
Postfilter On completion of all testing, the Postfilter provides a facility in which the administrator can update external databases or other information resources based on the results of the Xamime filtering outcome.

Groups; The groups facility allows the conglomeration of an array of dissimilar email addresses (not able to be compactly described using regular expression patterns) for the use as an ACL and/or test selector. A typical example of use would be the segregation of all the email addresses in a corporation into a per division group set. With each group thus permitting the administrator of Xamime to then apply unique rules to each corporate division.
Multiple administrators; Having multiple administrators allows for more than a single administrator to control various aspects of Xamime. The main administrator can create/modify/remove other administrators and their rights, even creating other main like administrators if required.
Maximum ACLs; The maximum number of ACLs dictates the degree of complexity of the site's filtering rule sets. Typically a single ACL is used per domain/group or set of filtering restraints.
Maximum ACL items; The maximum ACL items refers to the number of individual rules which may be contained within a given ACL.
Maximum Users;The maximum number of email users permitted with the supplied license of Xamime
Lexical Scanning; The ability to scan within an email and its respective attachments for words and phrases of interest.
Prefilter; Xamime provides a method/hook for administrators to gain access to the mailpack which is about to be processed (with envelope). This facility is typically used for operations such as integrating with SpamAssassin and Black/White list marking
Postfilter; Xamime provides a method/hook for administrators to gain access to the mailpack after all Xamime filtering operations have been performed. The Postfilter also supplies all filtering results and statistics using the standard URI format to the executed method. The Postfilter is frequently used to collect information from Xamime to populate reporting systems.
Spanning Storage; For large and/or long term email storage (as is required by several countries) Xamime now provides a spanning storage solution. Rather than storing all email in one location Xamime now can spread the storage across a span of partitions, disks and even computersSpanning computer storage via NFS, AFS or other network storage solutions. Using the unique storage destination specification system it's possible to load balance email storage to bias larger drives or even move storage to an entirely different location and still be able to search previous existing email, all this while your system is live. No more will you be cornered when your existing drive space runs out.
