What is it that differentiates conditions and actions? Is it simply that
actions are always the last line in a nest?
Conditions begin with `*'...
A scoring condition begin with `* w^x ' where w and x are two real
Could someone do this in Psuedocode for me?
* -1^1 .

| formail -A "X-Reject: High-bit character set in email"
If the mail (both body and header) matches the follow conditions (the
ending score is positive) pipe it to `formail -A "X-Reject: High-bit \
character set in email"' :
* First lower the score by 400 (-400^0)
* For each line lower the score with X where X is 1 first time and 1
second time and so on (-1^1)
* For each line with one or more chars that's in the range of [X-Y]
(`[a-z]' matches every char from `a' to `z') higher the score with X
where X is 10 the first time and 10 the second time (and so on) (10^1)
For instance, definitians of
:0 and the flags H and B (are these case sensitive?)
A line starting with ':' marks the beginning of a recipe.
It has the following format:
:0 [flags] [ : [locallockfile] ]
<zero or more conditions (one per line)>
<exactly one action line>
The `0' is from early in the procmail timeline... and if I understand
correctly it doesn't matter... Just use `0'...
The [flags] are indeed case sensitive...
`H' say that procmail should match the headers with the conditions and `B'
say that procmail should match the body with the conditions (and both
together say that procmail should condition both the header and the
`h' say that procmail should use only the header in the actionline and `b'
say that procmail should use the only the body in the actionline...
* What does this mean?
-400 why the -, and why would Era say that a "^0" after the -400?
Mathmatically, that is 1. dunno.
Well... I think that the `-400' is a typo since that would match a line
with `-400' somewhere in it...
But `-400^0' matches the `w^e' that is scoring...
Weighted regular expression conditions
The first time the regular expression is found, it will add
w to the score. The second time it is found, w*x will be
added. The third time it is found, w*x*x will be added.
The fourth time w*x*x*x will be added. And so forth.
So the `-400^0' will add -400 to the score the first time it is matched
and nothing the second time.
This will add -1 to the score for every line that matches...
[X-Y] Are these variables or flags?
Neither... It is a regular expression...
I think you will find the proper explaning in one of the manpages grep,
egrep, regex, regexp or some of the manpages refeered by those manpages.
And formail is a whole other subject I'll ask about later. :)
`man formail' will explain some of those things...
