Thanks! I think many folks learn a great deal from seeing
posts such as this [your] real life stuff. It may not be always
perfect or pretty like yours, but it works for someone who's
spent a lot of time developing it and *thats* worth a lot.
Personally I think $variables are a great leap forward
for folks learning about procmail, equivalent to understanding
weighted scoring, and especially the ability to set semaphores
with variables and test later for state.
I must be dumb but it took me almost forever to
understand that, in procmail, I could set a variable at one point
and then if/then test it later in the code to control processing.
I've been writing code professionally since 1966 (what a long
strange trip it's been) and it wasn't at all evident to me when I
first started trying to use procmail and read all the various
web-based stuff about it.
=> Okay, so now, back in the main rc, if I want to have a condition such
=> as Hammond/Peterson are discussing, I do:
=> * $ ^Received:.*[[(]209\.163\.100\.$OCTET
Any reason why you're not including the closing
paren/bracket at the end?
One thing I started using was my own variable $OR
(defined in my equiv of genvars) so I could do the following
scoring by adding in IP ranges as needed, cleanly and easily:
# IP ranges are for example only
OR="2147483647^0" # defined in initialization
:0
* $ $OR ^Received:.*[[(]209\.163\.100\.$OCTET[])]
* $ $OR ^Received:.*[[(]000\.000\.000\.$OCTET[])]
* $ $OR ^Received:.*[[(]000\.000\.000\.$OCTET[])]
{ some spam variable or action set here }
=> I use the other string-vars in various places to good avail.
What an understatement!
Thanks again,
- Don
