At our office we receive hundreds of spam letters per day with "[Norton AntiSpam]" in the subject header, followed by a random title. In example:
[Norton AntiSpam]Proactive Selling Techniques: Overcome your Barriers to Success
[Norton AntiSpam]和珅凭什么是最八面玲珑的秘书
[Norton AntiSpam]Have as much lenghth as you want
We have Spam protections installed, yet somehow these emails routinely manage to circumvent them and wind up in our inbox. I have tried to filter messages with [Norton AntiSpam] in the subject out, but this, too, is somehow overridden. I am using Thunderbird.
Whenever I search for a solution, I can find nothing but information on Norton Antispam software, which is apparently an anti-spam product. No matter how I phrase the search string, my results are for the software and have nothing to do with a massive spam campaign by the same title.
Is there any way to prevent these emails from overriding my junk filters?
Norton AntiSpam isn’t a seperate product anymore, it is included with Norton Internet Security, Norton 360, and the Comcast versions of Norton Security Suite. If you have one of those products, then Norton is flagging the spam by adding [Norton AntiSpam] to the subject line. If you don’t want to use that feature you can turn it off. Dave
Hi rbytbs,
What spam protections do you have installed? Everything you see with [Norton AntiSpam] appended to the Subject line is a message that has been filtered by Norton AntiSpam and flagged as possible spam. You have several choices. First, as already mentioned, if your email service provider offers a spam filtering option, use it in addition to any local program - it will eliminate much of the spam before you even download it to Thunderbird. Second, if you wish to continue using Norton AntiSpam and want to direct flagged messages to the Junk Folder, you need to create a Message rule in TB as shown below. In TB, click Tools > Message filters... and then click the New button in the Message FIlters dialog box. Another option available to you is to use the Junk Mail filter that is included with Thunderbird in place of the Norton AntiSpam program. The TB filter is excellent.
Thank you for the clarification, it is good to know where this is originating.
It is interesting that Norton puts anything it identifies into the In box despite the Junk identification, as Thunderbird does have a Junk mail folder and filters which normally do a good job of capturing spam. Norton seems to be taking whatever it recognizes as spam out of the Junk folder and dumping them in the In box, because the messages are still marked by Thunderbird as spam when it does so. This has baffled me, as Thunderbird is set up to automatically filter all messages it identifies as Junk to the Junk folder.
I have added another rule, telling Thunderbird to filter anything with Norton in the subject to the Junk folder. I had done this before, but it seems that I have not reinstated it since we upgraded our software. We will see if it works, or if Norton still supercedes Thunderbird's filtering.
Hi rbytbs,
Here is what is happening: Norton is filtering the messages before they are sent to Thunderbird, so by the time TB gets them, they would already have the [Norton AntiSpam] tag added. Because Thunderbird is not supported for email client integration, Norton does not automatically send spam to the Junk Folder, but will instead send it to the Inbox unless you create a custom message rule as descibed previously. I'm not sure what Thunderbird is doing, but whatever it is, it is after the fact. If your new custom rule does not solve the issue, I would recommend going with either Norton AntiSpam or the Thunderbird Junk Filter exclusively rather than using both.
Thanks again SendOfJive, I've really appreciated your help in this.
You're welcome.
