[linux-elitists] Procmail recipie to add X-ASN header

I've posted here previously about the merits of tracking spam by ASN.
I cobbled together a procmail recipie today which adds an X-ASN header
to mail. I use this in conjunction with a set of recipies derived from
Lars Wirzenius's rules via the Debian spamfilters package.
You should be able to INCLUDE this into your current processing. Do so
*before* you run SpamAssassin or any other tool which modifies headers
to obscure Received line.
Edit the SMTP_SERVER value to match the text entered by your (or your
trusted upstream) mailserver.
Note that this is a bit simple-minded and won't deal with mailing lists
If you're running a Bayesian classifier (e.g.: SpamAssassin, crm,
etc.), it should pick up this automatically and start classifying this
- Generates SENDERIP and REVERSE_SENDERIP
- Queries asn.routeviews.org for ASN
- Logs ASN
- Inserts X-SenderIP: header (dotted quad)
- Inserts X-ASN: header as "ASN-###" (a bare number is a less unique
