Today I'm going to answer some questions that people have asked me about my "Spam column" for DEMC Small Business Ezine regarding them. With regards to spam filters, onecan never have enough knowledge, so I do hope that thisarticle will clear up any misconceptions that you may have.1.
Don't spam filters ONLY apply to those who have NOT opted in?This is indeed a very sad misconception, Spam Filters doaffect EVERYONE who sends and receives email in someway or another. Whether you publish a FREE ezine OR aPAID ezine, it does not matter, if it is being sent by emailit affects YOU.
The biggest problem with filters is that they have NO way to detect that the email message is in fact "Optin", they actually base it on your headers.Should you use a third party list server, your chances ofbeing filtered are even greater, because of that reason.And this is how ALL filtering is based: By looking at the headers in your email message, by using a point systembased on the contents in your subject line as well as thebody. This can also be done by subscribing to a blacklist service that will provide them with a list of domains or hosts that have been identified as being used by spammers -such as http://www.spamhaus.org or http://mail-abuse.org/ AOL, Verizon and Accessus are widely known for using services such as these.
It should also be known that spam filteringprograms MAY also subscribe to these services, some doand some do not.2. I heard that spam filters don't apply to autoresponders,is this true?Actually they do, because if you send email using a thirdparty list server, and put your FROM email address in thefield rather than a FROM address on the third party's listserver - the spam filter will read it as being a "falsified"email address or header.
Because REAL spammers do it all of the time.3. Spam Filters do not target HTML ezines because theycan't read the code properly, is this true?Yes in fact they do, some more so than text ezines, this is because HTML ezines are considered to be more virusprone.
And NOT all list servers and email clients "clean"their email before it is sent. Meaning, even if you do nothave a virus on your computer, your ezine can still pickone up during the process of sending through your listserver.
This has been known to happen on "high traffic"list servers as well as FREE list servers, such as YahooGroups.3. Aren't spam filters ONLY used by large ISP's?Although it is very true that the majority of larger ISP's useSpam Filters (such as: AOL, Yahoo, Hotmail, Mindspring,Verizon, Accessus, Sympatico etc.) you will find a lot ofsmaller ISP's use them as well.
For instance, my ISP hasonly 900 customers and they do use them, although I've made it quite clear they are unacceptable on my account. The most "popular program' that ISP's use is called Spam Assassin.I hope this article has cleared up any misconceptions that you may have had regarding Spam Filters.
