Thank you Thomas,
I did not realize that it used the /s regex switch - that make sense. I
will need to go edit all of my BombRE's.
Your suggestion did work:
(?:^|\n)from:\s*_+
However, if you add scoring to it:
(?:^|\n)from:\s*_+=>1.5
ASSP rejects it as invalid Regex.

hmm.....
from\:.*\_
looks very bad - it is read like:
look for
from:
followed by anything any long (or nothing)
followed by
_
in the complete header
keep in mind: all bombRE's are using the /s regex switch (ignoring CR
and LF)
So, if there is an *underscore* anywhere after *from:* in the mail
header, the regex will match:
use
(?:^|\n)from:\s*_+
instead (collon and underscore don't need to be escaped here . but can be)
is read like:
look for
at the start or after each newline
from:
followed by any count of CR,LF,SPACE,TAB (or nothing)
followed by any count (but at least one) of
_
in the complete header
in your bombHeaderRe the line should be:
~(?:^|\n)from:\s*_+~=>60
the tilds are required in assp because of the used pipe (|) in the regex

No, I did not. I know regex fairly well, and this to me looks like a bug
or otherwise unintentional operation. I've commented out these lines in
my BombHeader for now.

Hi Scott,
Did you ever figure this out?
I'm no regex wiz like Thomas is, but what you have appears pretty simple
to me -- and I don't see anything wrong with it...
I tried
from\:.*\_
in testRE and see it matching everything too. I don't understand why.
I know this doesn't help you with why this is happening, but figured
that it would at least help to hear that you're not the only one whose
system generates that result.

I've been seeing a bunch of spam getting through my filter recently,
and
they all have the same thing in common: an underscore at the beginning
of the "From" and/or "Subject" lines. This should be really easy to
pick
up with bombHeaderRe, but something's not working.
Here's an example of the spam I'm seeing:
From:_Male Health
<support-team_0rk47mtncmz9bfpalcklzzn...@offer.market.ca
<mailto:support-team_0rk47mtncmz9bfpalcklzzn...@offer.market.ca
<mailto:support-team_0rk47mtncmz9bfpalcklzzn...@offer.market.ca>>>
Subject:_Size matters and we can help
Sometimes there is a space in between the colon and the underscore,
usually there is not.
Here is the regex I added to my bombHeaderRe:
From\:.*\_=>60
Subject\:.*\_=>60
However, I quickly realized that this was tagging EVERY email coming
through the server! For instance, here's an email:
From: Readly <rea...@news.readly.com <mailto:rea...@news.readly.com
<mailto:rea...@news.readly.com>>>
And looking at mail analysis, it's being caught by this regex, even
though there is no underscore:
BombHeader RE: 'highest match: "(matchlength:84) From: Readly
<readly@news.readly" with valence: 60 - PB value = 60'
matching bombHeaderRe(file:files/bombheaderre.txt
<file://files/bombheaderre.txt>[line 188]):
'From\:.*_'
Any idea what's going wrong and causing this?
