OK. Weve been plugging all the spam holes provided free of charge in Exchange 5.5. We are at the latest service pack level.
Dilemma : a spammer is still getting through. I see entries in the queues from him. We’ve added several email addresses to the filters window, but this one has a blank originator field! In the details window, it has <> for originator. Does this mean that he’s stolen someone’s username / pw? In the MTS-ID field it says c=US;a= ;p=[ myCompany’sName ];l=[ myCompany’sServer-FQN ]. I cannot add his email to the filter because it will not accept a blank email address. The destination host (hotpop[…].com) is not housed with us. I will provide more info if necessary. Thanks in advance!
