Anti spam

Hello

I experience strange behaviour of anti spam in NIS2008 - messages from users added to my white list may be marked as spam if keyword filter finds match.

I spent few days with customer support without any solution.

One of representatives tried to explain to me that it is correct, but was unable to explain purpose of white list in that case ;)

Anyone of you experienced that? Do you have any solution?

kind regards

Qba

Re: Anti spam

I believe that is the correct behavior. 

 

I had the same type of issue when someone who was on my white list sent me a message with a subject line that could well have been interpreted as spam.

 

Purely conjecture, but since email addresses can be spoofed, the Norton anti-spam engine may be designed to protect against known spam keywords and then override the white list.  You could look at it two ways:  a false positive or a double layer of protection. I prefer the latter.

 

For me it was no big deal to mark the message as "This is not spam".

Correct.

Ant spam sees white list stronger than the blacklist

Re: Anti spam

Thanks for answers.

Marking message as "this is not spam" only moves message to inbox folder and does not affect any future messages from that person.

When receiving about 100 spam messages a day it's hard to track if there are messages important for you.

Please help me understand what is white list for in that case?

Re: Anti spam

Qba,

 

In my case when I mark a message as "This is not spam" it is then placed in the white list and those email senders are not marked as spam going forward, unless of course something in the subject line or perhaps even the header triggers the antispam engine.

 

Is there anything you notice about your "problem messages" that could trigger the spam alert?

It is the way it really works. There must be something else.

Re: Anti spam

Of course there are words that can trigger spam alert.

Maybe I explain not clear.

Let's say I set keyword "green" in spam filter and messages with word "green" should be placed in spam folder.

And let's take 2 people - user1@domain.com and user2@domain.com . And let's user1@domain.com add to white list.

And now both sends message to me with word "green"...

What's difference ? According to you both messages should be placed in spam folder?

So what's advantage of placing user1 at white list?

Re: Anti spam

Hi Qba,

 

The advantage is that if user1@ dom sends a message one time which triggers the spam filter, that user is not relegated to the spam list forever; you have the option to add that person to the white list.

 

As long as future messages from user1@ dom do not contain spam triggers, then user1@ dom will always come though in the normal fashion.
