qmail on RHEL3, changing max messages sent per time period
I have a server running Red Hat Enterprise Linux 3. I've installed qmail (mostly following Life With Qmail and qmailrocks.org's advice and instructions). I have a few questions:
- I would like to limit how many messages any particular user/connection can send per minute (second, hour, whatever). I've looked through the qmail man pages and website(s) but haven't found a way to limit this. Should I be looking somewhere else?
- are there any SMTP test programs or sites that I can use to check my server (security-wise, effeciency, etc -- something like DNSreport.com but for SMTP).
Can I use some function within qmail itself, spamassasin or clam-av to limit the message rate from a particular client? (i.e., "client 10.10.10.1 can't send more than 50 messages within an hour's time").

the solution presented wouldn't really help you there. jrs is suggesting that I use iptables to limit the number of concurrent connections. iptables' --limit option will work for this but it works on a per second basis, not hourly or daily.
damn... so is there any other way to protect the server from email abuse from inside clients ?
MaRIOsGR - there is, but you should start your own question. =)
