1. FEATURE: Spam Solutions II

The response from our first spam story was tremendous. Apparently I'm not the only one who has been inundated with spam. Many readers sent in other tips and tools that they use to reduce their spam load. As promised here's another installment of Spam Solutions. For those of you just tuning in, here's the first installment:

Spam, or unsolicited email, has exploded on the Internet. With a marginal cost of zero email advertising and solicitations have a heady appeal to marketers hoping to sell their wares. Spammers use special spiders and software, and buy huge targeted email lists to email tens of thousand, and yes millions of users at a time. If only a small percentage of users respond, spammers can make money.

Email program makers like Qualcomm (Eudora) and Microsoft (Outlook) offer partial solutions. Eudora users are encourage to enable "Moodwatch" or create filters to redirect potential spam to other mailboxes.

Outlook users have "Junk E-Mail" and "Adult Content" filters that work by searching keywords and can download filter updates, but these aren't 100% effective. That urgent business proposal from Uganda still seems to still slip through. As fast as users tweak their filters, spammers find another way in. What users need is a more robust approach.

* Steps to Stop Spam

First, avoid making your email address easy to harvest. Consider using Hotmail or a similar account when posting messages to the web. Use your primary or business account only for communicating with colleagues. Second, disguise your email by spelling it out, (andy at jupitermedia dot com) using JavaScript, or embedding words that users remove before sending you email.

Third, don't let the smammers know you are there. Don't reply to spam expecting to be removed, you've just confirmed your existence. Also, turn off automatic HTML image downloading in your email program, the default (at least in Eudora) of on, automatically registers that they've got a live one at the other end of that email. When I turned off "Automatically Download HTML Graphics" in Eudora, the amount of spam I received went down.

* Spam Software

There are two approaches to filtering unwanted spam: server-side and client-side. Server-side solutions nip the problem at the ISP level before they ever get to you. Here are some solutions:

Brightmail - Spam Wall, popular ISP option works with sendmail

SpamShield - Perl based filtering for sendmail

Sendmail anti-spam measures (be sure to get the latest version): lets the spam flow to the ISP, but you redirect your email to them, they filter it, and your retrieve it back from them.

* Client-side Spam Solutions

Client-side solutions abound. Other than Spamfire and Spamassassin that we mentioned last time here are some other client-side spam solutions (all Windows): - Choice mail, permission-based approach - Matador, combines techniques - Mail Washer, freeware - Spam Killer from McAfee
