sos4eset 1 Posted May 26, 2017 Author Share Posted May 26, 2017 Can you show specific instructions? I am trying to find exactly how to do this but cannot find specifics. Can you elaborate with step-by-step? For instance where to start--is this an "Email Client Protection" setting or a "Mail Server" protection setting?

ESET Staff filips 44 Posted May 26, 2017 ESET Staff Share Posted May 26, 2017 Rule settings are on page Advanced setup/Server protection/Rules 1. Add new rule 2. Select conditions - By message subject, By message sender 3. Enter values that you want to block 4. Select action + check Log (you can test it with No action for a while) more info http://download.eset.com/manuals/eset_emsx_45_userguide_enu.pdf Link to comment Share on other sites More sharing options...
