We have ESET Mail security for exchange on our mail server.
Havent really tinkered with the settings much - but have enabled the antispam facilities.
I can see its pretty busy knocking down the junk - the only ongoing issue I have is that it doesnt like xtra email.
They all get blocked with the message "Sender has spammy reputation (100%)" - no matter who they actually come from at xtra - so it doesnt like the domain.
I added xtra.co.nz to a whitelist - but that hasnt prevented it from rejecting mail from xtra.
Does anyone else run this product or have some ideas on xtra emails?
