1.4.3 Application of user-defined rules
Protection based on user-defined rules is available for scanning with both the VSAPI and the transport agent. You
can use the ESET Mail Security user interface to create individual rules that may also be combined. If one rule uses
multiple conditions, the conditions will be linked using the logical operator AND. Consequently, the rule will be
executed only if all its conditions are fullfilled. If multiple rules are created, the logical operator OR will be applied,
meaning the program will run the first rule for which the conditions are met.
In the scanning sequence, the first technique used is greylisting - if it is enabled. Consequent procedures will always
execute the following techniques: protection based on user-defined rules, followed by an antivirus scan and, lastly,
an antispam scan.
1.5 User interface
ESET Mail Security has graphical user interface (GUI) designed to be as intuitive as possible. The GUI gives users
quick and easy access to the main functions of the program.
In addition the main GUI, there is an advanced setup tree which is accessible from anywhere in the program by
pressing the F5 key.
Once you press F5, the advanced setup tree window opens and displays a list of configurable program features.
From this window, you can configure the settings and options based on your needs. The tree structure is split into
two sections: Server protection and Computer protection. The Server protection section contains items
concerning ESET Mail Security settings, specific for Microsoft Exchange server protection. The Computer
protection section contains the configurable items for the protection of the server itself.
