Hey y'all
An associate of mine has experience with postfix, and was wondering if qmail blocks
messages at SMTP that fail to meet valid criteria. See the postfix log summary generated
from his machine, below. I'm aware the qmail toaster comes with support to use the
following facilities to block bad messages: RBLs, SPF, domainkeys, simscan, clamav,
spamassassin, SURBL. But does it block messages such as the "Host not found" or
other criteria? If not how to configure? I'm aware Greylisting isn't part of the
qmailtoaster.
The second question, does anyone know of any utilities that can generate
reports like this from the qmail logs?
Thanks!

Right now Toaster blocks at a SMTP level any connection that fails the
RBL check defined by the servers in /var/qmail/control/blacklists. It
will also dump the SMTP connection if any of the criteria are met in
your CHKUSER options in /etc/tcprules.d/tcp.smtp.
And no; you have the web page gui that shows some mail stats, but the
logging has ALWAYS been clunky in Qmail itself. you can use some extra
programs like qmail-analog, but even then they're crappy at best, IMHO.
I guess you could write a script that would parse the log and count each
type of entry. No one I know of has done so yet.
