We do treat the action of moving a message to the spam folder the same as clicking the "Spam" button. This is fairly common. It can make for mistakes if someone is dragging a message and accidentally drops the message in the wrong place. We've seen instances where someone attempts a bulk move and accidentally files hundreds of messages into Spam, and a few minutes later refiles them elsewhere. Another type of incident we've seen is sometimes a user has switched clients and the new client decides that messages previously in the Inbox are now spam, and refiles them to the Spam folder. This could also generate a spam report in certain scenarios. And I'm sure we've all seen that users can (and do) treat the "Spam" button as delete. -- Alex Brotman Sr. Engineer, Anti-Abuse Comcast From: mailop [mailto:mailop-boun...@mailop.org] On Behalf Of timrutherf...@c4.net <mailto:timrutherf...@c4.net> Sent: Tuesday, November 07, 2017 10:28 AM To: mailop@mailop.org <mailto:mailop@mailop.org> Subject: [mailop] Comcast Feedback Loop emails that look legitimate Hello all, We are on the Comcast FBL and occasionally get abuse reports from Comcast through that service. It is my understanding that these reports are generated automatically when the customer reports an email as spam. However, we have seen several occasions where the messages are clearly not spam. In some cases they are a reservation confirmations (something the customer just purchased), invoices from companies they deal with on a regular basis, or even general email correspondences. I'm wondering if there are any other actions that trigger a spam report and consequently a FBL report. IP reputation, message content, 3rd party antivirus actions, etc. ? The messages come from feedbackl...@comcastfbl.senderscore.net <mailto:feedbackl...@comcastfbl.senderscore.net> , which makes me wonder if they have some algorithms in place. Thanks in advance for any input! Tim
