I get spam from a number of sources that are all showing up in Outlook as from a person's name - sometimes subject is unoffensive like "award" or "you are invited", but sometimes pretty bad with a long subject of misspelled sexally suggestive subject. Sometimes they are pharmaceuticals misspelled. BUT they are all coming in last from @yahoo.com, which is my email domain. No spam filter catches them - not at yahoo mail nor in Outlook, using Norton 360.
The mails are going thru a chain of IPs, but all seem to originate at one IP address which I thiink is: 10.193.11.119
Will blocking anything from that origin even though it goes thru several (and always different) Ips along the way? If so, how do I do it? Or please help me on hopw to stop this any way I can.
Thank you!
