Hi List, I'm looking for some support libraries that will help me to parse sendmail logs.
I'm confused about whether i need a "parser" per se, and if i do which parser to use. I found this website http://nedbatchelder.com/text/python-parsers.html which compares a slew of python parsers. Initially I'm wanting to be able to report on who the recipients of a particular email where based on an email address or host. Another report I'm interested in creating is who sent email to a particular email address. These simple reports i have written already using unix tools like grep, sort, awk : --- 1. grep 'email_address' ../maillog* |awk '{print $6}' |sort -u |awk -F: '{print $1}' >phis.txt 2. for i in `cat ./phis.txt` ; do grep $i ../maillog* >>./maillog; done 3. grep "to=<" maillog |awk '{print $7}' |sort -u >recipients 'email _address' is user supplied and it would be nice to default to just maillog but to let the user specify maillog.* or maillog.[1..6] I whipped these up in a few minutes. 'phis.txt' contains a unique list of message ID's 'maillog' is a filtered raw log of matching lines based on the message ID's. 'recipients' gives me a list of email addresses, sometimes with multiple email addresses on one line comma separated. --- I really want to just tidy this up into a python script as a programming exercise. so that's the background. How do i go about representing the structure of the sendmail log file to my script. I'm imagining having to filter through the logs and building up some kind of data structure which i can use to report from. should this just be as simple as a dash of regex and str.split() ? or are there better tools that provide a richer framework to work within? I would love to extend or write further scripts to analyze the logs and pick up things like someone suddenly emailing to 500 people. but crawling before running seems like the order of the day. Cheers, nibudh.
