[Bug 4045] New: Detection of "obvious" spam
http://bugzilla.spamassassin.org/show_bug.cgi?id=4045
Summary: Detection of "obvious" spam
Product: Spamassassin
Version: 2.60
Platform: Other
OS/Version: other
Status: NEW
Severity: enhancement
Priority: P5
Component: Score Generation
AssignedTo: dev@spamassassin.apache.org
ReportedBy: amspammed@oil4lessllc.com
Every time i see random characters in name field of return path,
i find that the e-mail is SPAM.
*Please* modify your software to sense this glaring attribute.
Three or more consonants in a row, with table lookup for the three
consonants exceptions (ie: Tomaschewski).
As far as i am concerned, this attribute should be scored with 12 points.
**
It might be helpful to allow a different number of points to each scored
attribute and that the "learning" process change that weighting.

This is prone to false positives and spammers will just adapt and never put
three consonants in a row.

If you feel that this rule will be effective for your site's e-mail, you are
free to add such a rule to your local configuration. However, I will point out
that it will hit your own e-mail address (amspammed@oil4lessllc.com) four times:
ams ssl sll llc.

And in any case there are a handful of available rulesets that catch this
sort of thing quite nicely.
Of course, they are less useful on Polish, Russian, and similar languages
which are vowel-deprived.
