I'm asking to me from some days ago, after see my logs, what's
happening with some mails.
I get the logs of qmail-smtpd and qmail-scanner (qmail-queue.log)
and filter it for one day exactly, for example, 06 November.
well, I get the total incoming smtp connections with:
cat qmail-smtpd06.log | grep "tcpserver: pid" | wc -l
I get the RBL bloqued connections with:
cat qmail-smtpd06.log | grep "rblsmtpd:" | wc -l
and I get the total mail processed by qmail-scanner with:
cat qmail-queue06.log | grep "+++ starting debugging for process" | wc -l
The numbers that I got are:
Total incomming: 105963
Blocked by RBL: 82611 (then, total allowed: 23352)
Processed by qmail-scanner: 17075 ----> then, 6277 connections
are lost between qmail-smtp and qmail-scanner.
where are they?
