The server configuration is stored in the notes.ini file on the server. This file contain information about add-ins in the EXTMGR_ADDINS line. The ESET Mail Security LMON.dll add-in is loaded into protected Domino server tasks. It is loaded when each Domino server task is started. This way, the add-in is notified about every important event, for example: a new connection, a new message in a mailbox, when a file in a database is accessed, etc. During the ESET Mail Security installation, LMON.dll, LMON_SCANNER.exe and LmonLang.dll files are copied into the Domino directory (the file LmonLang.dll is only present in localized versions of the product).
