If they ever publish a cell phone directory and charges continue to be accrued by the receiving party, I predict a return to the concept and use of debtor's prison. |

It's also necessary to have good spam and virus filtering at
the ISP and 3rd party email account level. My Bigfoot account, after going through Bigfoot's filtering, goes through my local ISP filtering. The result is, although I post to usenet with a valid Email address, I receive less than 5 spams per day. I filter out all the Korean junk and the usual offensive headers and ISP sources. Small, local ISPs usually have better filtering than the big box accounts, who just may be *adding* spam to your account. If your ISP is forwarding alot of spam to you, you're not being served well.... My local ISP (Seanet) has up-to-the-minute virus filtering, and will forward all infected Emails with the virus or worm stripped, flagged and identified.

On Topic: Fighting SPAM, here and in email
I recieve way too much spam, more than 100 per day on avg. I have MS IE set
up with message rules to route some of the junk to a junk folder. When I block this stuff from being downloaded from my ISP server it eventually piles up and slows my mail account to a crawl. So my question, do the spam blocker programs make spam mail pile up on the server ? Ron White My boatbuilding website is: www.concentric.net/~knotreel |

So my question, do the spam blocker programs make spam mail pile up on the server ? No. I use a program called Mailwasher (http://www.mailwasher.net)...it not only deletes spam from the mail server, but it also "bounces" it back to the sender as undeliverable. I now have it configured to do it autmatically...I never even see most of it. All spam blockers need input from you to know what is and isn't spam, btw...so it'll take a little time and effort on your part to get any of 'em working. And you'll never be able to cut it down to -0- without blocking all email from every other ISP...'cuz spammers use bogus (and sometimes real) MSN, AOL, Yahoo, Earthlink return addresses. But a good one will block all spam from web domains...and allow you to manually delete the rest without downloading it.

So my question, do the spam blocker programs make spam mail pile up on the server ? This is going to sound like a commercial for one program, but it really isn't! I'm just a satisfied user of an application from New Zealand, Mailwasher Pro. First, I have to observe that you are *lucky* to get only 100 spams a day! I regularly see 10 times that pass across my server. In my opinion, one of the single biggest problems with spam filters is the issue of "false positives." Many ISPs have their own spamfilters in place. I have problems with this approach because the user has no control over what gets blocked, and on what criteria. For example, there is a fine e-newsletter about the Sacramento Delta, "Delta Scuttlebutt." I forwarded a copy of the letter to my wife at work; it was blocked by her employer's ISP because it contained the word "butt!" I have long used spam filters on my email client (Eudora), but using that approach alone, I'd still have to download all the crap before filtering it. With Mailwasher, which I've been using for several months, I download only enough headers from the server to determine whether they are spam or legitimate. Then Mailwasher deletes them from the server. At present, I am using a combination of my own blacklist, two network blacklists (SpamCop and ORDB), a proprietary real-time blacklist, a whole arsenal of RegExp filters and a whitelist of legitimate senders. I have 100% confidence in several of my filter expressions, so I tell Mailwasher to delete those spams without any intervention from me. Those that remain take just a few seconds to skim over before deleting. There's no "perfect" spam filter, but for my purposes, Mailwasher comes pretty damn close. HTH, Joe Parsons |

Thanks, I'll visit that site. I really like the idea of bouncing it back and
possibly causing some annoyance for the spammer. -- Ron White My boatbuilding website is: www.concentric.net/~knotreel |

I've used the freeware version of Mailwasher, which I got before the Pro
version was available, and for which I made a $20 "donation," for about a year. I've also been very pleased with it. It occasionally mistakes a legitimate email for spam--for instance, I've made *free* a wildcard, which caused it to bounce an email from a friend whose last name is Freeman)...but that was easily overcome by adding his email address to the "friends" list. I prob'ly have at least 200 wildcard expressions, domain names and subject line filters in place...and I just keep adding on as necessary. Since spammers continually change domain names and email addresses, I've also configured it to delete those that don't show up again within 90 days, which keeps the list down to a manageable size. However, it seems to me that if I can cut spam by 90% with a freeware program, ISPs have the technology to do it before it ever gets to our mail servers. And it shouldn't require any filtering...only bouncing everything to 10+ addresses from the same sender. Legitimate senders who want to send new baby announcements etc to half the world would still be able to do it by just limiting 'em to batches of 9 at a time. Prob'ly wouldn't be foolproof, but would get rid of 90% of spam...and have the added benefit of clogging up the spammers' servers with their own junk coming back to 'em.

Don't bounce the email, very very rarely will the address be legitimate.
All you will be doing is contributing to the number of useless email being bounced around. "Ron White" wrote in message ... Thanks, I'll visit that site.
