Well, a theory is that the resources saved by rejecting more spam will more than offset the resources used by the perl interpreter. There are, of course, non-perl qmail-smtpd replacements, including my own :-) But qpsmtpd has a lot of momentum and you gain from that. mm (not really here nor there)

All the other qmail-queue replacements i've tried, including qpsmtpd, where just too expensive regarding system resources. Most solutions involving perl will simply not do, at least for me, on account of perl overhead. Right now i have several production environments, one of which is rather large, and i've been rather happy with the implementation outcome. That setup includes qmail-ldap with some patches for greylisting and greeting delay, simscan with a patch to handle dspam internal quarantine engine, dspam with a patch to allow user checking/address alias mapping, clamav, maildrop for server side filtering and finally dovecot with Johannes dspam plugin. Besides the regular locations for all that software, you might consider taking a look at the set of patches i mentioned.

FWIW, I'm using it with dspam 3.6.8 from debian. But I have a per-user setup, if you want a virtual user setup you probably need to do a bit more work since the plugin will actually need to call the dspam binary with a --user argument which requires a plugin modification. I know that some people have done this modification, but I haven't received any patches. If you get it to work a patch would be welcome. johannes Basically my primary objective is to prevent spam and today i got an interesting link to it: http://searchenterpriselinux.techtarget.com/tip/0%2C289483%2Csid39_gci1235770%2C00.html and http://www.oreillynet.com/pub/a/sysadmin/2005/09/15/qpsmtpd.html I think this method is more reliable since I am playing with a production server.

[Dovecot] How to integrate dspam and dovecot
Hello all, I am currently setting up a new mail server with Qmail, OpenLDAP and Dovecot in CentOS-4.4. Qmail version is 1.03, OpenLDAP is 2.3 and Dovecot version is dovecot-1.0-3_50.rc27(RPM). I have successfully installed and tested it. But I have two issues with the current setup: #1. I am using dovecot LDA and configured the OpenLDAP such that the mail be delivered to the virtual users through a script. This script is saved in /var/qmail/bin/deliver.sh and the contents is as follows: /usr/bin/dspam --stdout --mode=tum --deliver=innocent,spam --feature=chained,noise --user global |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $RECIPIENT || exit 77 This script name is mentioned in each user's deliveryProgramPath in the LDAP. I am not sure whether this is the best approach of using dovecot as MDA. I tried to include the following contents in /var/qmail/control/defaultdelivery : |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $RECIPIENT But it seems that this is not working as desired. Please comment, if I have gone wrong anywhere. #2: I wish to use dspam to filter out the spam messages, but I am unsure whether the dspam plugin mentioned in http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration is already in the dspam version I am using. If it's available please give details to configure it. Kindly share ideas. regards Manilal. -- Better to light one candle than to curse the darkness.
