16.3 Analyzing Other Logs

There's nothing like qmailanalog for the qmail-smtpd logs, mostly because the useful information in them varies so much depending on what auxiliary programs and what patches are in use. I've written some Perl scripts that read through the logs and count the rejection messages for each DNSBL in use, but they rarely reveal anything interesting beyond the dismayingly large amount of spam that's showing up at my mail servers.
