Spam detection is getting worse?

Over this year I have logged the number of spams I have received, and the percentage which were tagged by Plusnet. They were as follows:-

Month Total received %age tagged
Jan 355 96%
Feb 314 92%
Mar 433 89%
Apr 432 88%
May 225 90%
June 142 66%
July 370 43%

The last 2 nonths has seen a dramatic drop in the spam filter effectiveness. Is there a fault? or is there some other explanation?

Spam detection is getting worse?

Spam detection is a black art and is getting increasingly difficult over time as the spammers are using more and more sophisticated methods to bypass the spam filters.

There is also the problem of making your spam filters too aggressive resulting in more legit emails being marked and also the processing power needed to scan the ever increasing volume of emails.

This is not a problem just for PN but on the internet in general. ISPs and spam detection software is always in catch-up mode and given what you ahve seen, it appears the spammers have the upper hand at the moment.

PNs email platform is suffering with the volume of emails hence why they are upgrading the whole architecture (which caused the loss of 700GB os emails reported elsewhere) but this new kit should allow them to improve the scanning of viruses and spam.

Spam detection is getting worse?

Spam filtering is working fine for me but I do not get huge volumes of email so sorting through is easy.

It is a huge challenge to decide what is spam and spam for one person is not spam for another. What should be done is target persistent ISP sources or even filer outgoing emails.

Also i do fel people themseves should make efforts to avoid spam i.e. different email addresses on usenet, web sites etc.

PS. I am in desperate need of some viagra and a rolex watch. Stop filtering my mail :twisted:

PN spam detection is getting worse.

My work e-mail is scanned by postini, it is not getting worse.

I have to agree. I get a little bit of spam and even though I have spam settings set to "high" I don't recall it tagging any at all in recent weeks.

Spam detection is getting worse?

I'm still getting a lot of mail tagged as spam, but I don't have my filters set to 'high'.. maybe they've started working in reverse mode. Smiley
But I'm getting a lot more spam than I did even a month ago, and recently I've noticed more that isn't tagged.

I've got Russian girls wanting a date too. Anyone wa\nt one of them?

Low/High/Medium etc. hasn't mattered for a while now, I believe.

Spam is unfortunately getting more difficult to detect, it would appear as all my usual packages seem to be failing to pick up on some of it.

Do we know what they actually use to do the spam filtering?

Did they turn on blacklisting, there was some talk of it a shile back?

Maybe they could sign up to ORBL or similar to block spam; as a subscriber they may even get a discount in asking to be removed from the list. :-)

Sorry for being dense, but does PlusNet have spam filtering on all accounts by default? The only references I can find in the support pages talk about going to your email settings page to activate/deactivate, but I can't see anything about spam there. (There does seem to be the option to have spam/virus filtering as a pricy extra-cost "Services Package".)

Look to your left, click 'Services' then 'Spam Filtering' which take you to https://portal.plus.net/my.html?action=configure_spam_filter

When I go to that section I just get a sales message:

I'm not going to pay extra for it!!!

I'm already on PlusNet Broadband Premier Option 1 - £21.99(monthly). Shouldn't spam filtering be included?

Actually, looking here:

http://www.plus.net/residential/broadband/

it says spam filtering is included in this package.

Is something wrong with my account?
