For several weeks, Bitdefender has not been catching multiple spam e-mails I've been receiving daily across 3 Yahoo-related e-mail accounts. Most of these originate from an IP segments in Australia, such as 40.107.138.117, 40.107.96.88 and 40.107.220.85. They are all pretty obviously spam, but keep getting through. I've reported hundreds to Bitdefender by selecting "is spam" in Outlook, to no avail. How do I escalate this issue to get it resolved? FYI - I've kept copies of most of them ...
