I've been getting a lot of spam email lately. Either that or I've suddenly become incredibly interested in stock tips and penile enlargement and don't remember signing up for 45 email lists.
The spam filter that I use delivers these messages to my inbox, but tags them as spam, and explains why it thinks so. This raises the question of why it would still deliver them if it knows they're spamů but that's another issue. Perhaps I need a new spam filter, or learn how to use this one better.
One interesting benefit of this procedure, however, is that I get to learn exactly what makes a spam message spam. Besides the fact that if I actually knew someone named Leroy Krumpett, they probably wouldn't subject their email "Good Morning Leroy Krumpett".
There are a number of criteria that trigger spam filters, only some of which are needed before the message gets classified junk mail. These criteria are sorted into categories, and assigned a certain number of points each. The following is a message I received that was marked spam.
|2.3||FROM_LOCAL_NOVOWEL||From: has series of non-vowel letters.||So maybe I should stop emailing myself test messages titles things like dgbvntdbvntdnbdv.|
|0.9||DATE_IN_PAST_12_24||Date: is 12 to 24 hours before Received: date|
|0.6||BODY_ENHANCEMENT2||BODY: Information on getting larger body parts||Why is this only .6 points? How often do you send a legit email about getting larger "body parts"?|
|2.0||RCVD_IN_SORBS_DUL||RBL: SORBS: sent directly from dynamic IP address|
|1.7||RCVD_IN_NJABL_DUL||RBL: NJABL: dialup sender did non-local SMTP|
|1.1||URIBL_SBL||Contains an URL listed in the SBL blocklist|
|3.4||URIBL_JP_SURBL||Contains an URL listed in the JP SURBL blocklist||Why is this one worth so much more? I guess having more letters makes it a more hard-core blocklist.|
I don't know what some of these mean, but I feel I could suggest some ones to add that would be very helpful:
|1.4||SPAM_LINGO||Contains any or all of the following spam-likely words or phrases: Stock tips, penis enlargement patch, Next Big Thing, sexual performance, refinance|
|2.4||SPAM_LINGO_ BADGRAMMAR||We approve you loan, It ready, Maintain you erection|
|3.1||AFRICAN_BANK_HOAX||Begins with the greeting "Dear Sir or Madame"|
|4/0||MENTION_VIAGRA_ ANYWHERE||Let's see... has anyone ever used the word "Viagra" in an actual email to a friend, family member or business associate? Nope. Not ever.|
