I'm trying to construct a recipe to snag a specific pattern in the
Message-ID header line. A sample Message-ID looks like:
# Message-Id: <E1BO2fg-0002He-HQ(_at_)ocjnet(_dot_)com>
My recipe is:
A=[a-zA-Z0-9]
:0
* $ ^message-id:[ ]<$A$A$A$A$A$A$A-$A$A$A$A$A$A-$A$A
spam
I can't seem to isolate the "-". I've tried "\-", "\\-". [-], [\-]. I've
even tried assigning F="-" and including $F in the recipe.
Grep man pages state that a "-" included in a class should be placed last
inside the [], so I guess [-] would not be expected to work.
That direction has to do with classes inside square brackets, e.g.,
"[A-Z-]", which would be A through Z and a hyphen. To match a hyphen
in procmail generally, you just use a hyphen. There's nothing magical
about the char used outside a [char class].
I appears to me that procmail is interpreting the hyphen as part of a
class, ie "include 7 (numberletters) through 6 (numberletters)" or
something similar.
No, I really don't think it's doing that.
I tried something in my test harness to what you have:
A=[a-zA-Z0-9]
:0
* $ ^Message-ID:[ ]*<\/$A*-$A*[^>]*
{ HYPHEN = "$MATCH" }
And ran it on some spam I have sitting around:
7:38pm [~/Mail] 730[0]> harness myspam | grep HYPHEN
procmail: Assigning "HYPHEN=e5ms75u-1601-3yas--j701$156vo(_at_)o62m3t6d3pfc"

So off-hand, I'd say something is eluding you, but not what
you think it to be. :-)
