I implemented the postscreen capability on a small MTA I run for friends and family. Once I got postscreen configuration producing the results I wanted, I soon tired of watching the detailed maillog to see how postscreen was operating. So I wrote a quick shell script to summarize the log file and give me an overview of how well postscreen is working.
I offer the script to anyone who would like to use it. One company I worked for would not allow open source software into the company unless there was an explicit license on the software, so I put the BSD license on the script. You can download the script from here: http://archive.mgm51.com/sources/pslogscan.html Here is the sample output that pslogscan.sh produces: Scanning /var/log/maillog All "incoming" log records: 5789 All "status=sent" log records: 1873 All "status=deferred" log records: 10 rejected: 3906 (67%) PASS NEW log records: 390 PASS OLD log records: 1762 WHITELISTED log records: 109 BLACKLISTED log records: 0 Protocol errors: HANGUP log records: 2980 PREGREET log records: 187 BARE NEWLINE log records: 1 COMMAND TIME LIMIT log records: 8 COMMAND PIPELINING log records: 1 DNS black lists log records: zen.spamhaus.org: 3174 dnsbl.sorbs.net: 1338 b.barracudacentral.org: 2759 DNSBL blocked log records: 2410 DNSBL rank 3: 493 DNSBL rank 4: 0 DNSBL rank 5: 0 DNSBL rank 6: 938 DNSBL rank 7: 0 DNSBL rank 8: 0 DNSBL rank 9+: 979 DNSBL blocks by domain: example.com: 393 example.biz: 69 example.net: 1699 example.info: 108
