Can Wall be used to avoid Denial-of-Service (DOS) attacks?
Yes. To do so, use the “Mail Flooding” function. This function (currently available for iQ.Suite for Domino only) defines the actions to be executed when the number of emails received within a configurable time window exceeds a given limit. Use the Operations/Avoid Mail Flooding tab to set the actions to be executed, the count mode, as well as the time range and the number of mails within that range. All mails exceeding the maximum number of mails allowed for the time range are blocked. Example: With the count mode set to All, the number of mails set to 1000 and the time range set to 5 minutes, the 1001st and all subsequent mails arriving within 5 minutes will be blocked.
