I know this is not at all zimbra related problems.But can you give any links related to this? Also on which port these spams are passing through?
Can i block the port 25 only open to my zimbra server??If you have any articles to solve such situation, it would be very much helpul.
Again Iam sorry to ask you a non Zimbra question.
Thank you
