Can someone point me to URLs or etc that discuss using procmail for
finding a percentage of unreasonable stuff in subject line.
Did you try looking in the Content-Type: and/or charset= ?
Do you mean that you get multiple Subject: fields? Or you just
show us a collection of examples?
Maybe:
:0 H
* ^Subject:.*^Subject:
/say/it/is/a/spam
I posted a variety of the type of subject lines in which I see a high
number of unreasonable characters. At least unreasonalbe in the
sense they are not likely to appear in a legitimate message to me.
Even numbers are unusual in personal mail subject lines. At least
above a certain percentage of total chars in subject line.
What I was looking for is a method to analyze the subject line to
determine if there are more than a certain threshold of unusual
characters.
The first example above shows something like 39 chars. Of those,
some 13-14 seem somewhat unusal for subject line:
[$]&#;@]...>;
It represents something like 35-40 percent of the total.
I'm intereresed in a script called by a recipe that makes such an
analysis.
