It is written in perl and is modular but resource utilization is very high in terms of cpu and memory usage. It checks for: early talkers spam helo max limit to unrecognized commands dns resolve tarpit limit badmailfrom badrcptto dnsbl recipient verification from radius for local domains spamassassin grey listing and lot more. By using above filters I have been able to filter out more than 70% of the mails that my MX receives. And some modules can reject mails just by reading the mail headers even before getting the data. This does save bandwidth on my link. Qpsmtpd finally delivers the mail to qmail-queue. However I have patched qmail to integrate it with qmail-scanner. Qmail-scanner then calls clamdscan which checks for virus with the clamd running on another server. But obviously this system is not fast!!! and is heavy on resources and that's the only issue I have. User validity check against radius is the main feature for which we are using qpsmtpd. Can you one suggest me a better mta than this with all those features :) regards, Bikrant On Sunday 03 April 2005 14:56, vaida bogdan wrote: > Hy, I woule like to know which mail setup that has the following > characteristics you use for primary mail servers: > - fast and reliable delivery > - anti spam/phishing/virii filterring > > I would like to reduce the number of packages used in my current > configuration or possibly change it as I have a hard time debugging > problems. > - postfix+qmail maildir > - courier imap > - razor agents > - procmail > - spamassassin > - amavis > - clamav > - cyrus sasl2 > > Thanks, > Bogdan > _______________________________________________ > freebsd-isp@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-isp > To unsubscribe, send any mail to "freebsd-isp-unsubscribe@freebsd.org"
