I've got an extensive qpsmtpd setup - the Perl-based precursor to haraka - and I've been meeting to port it over for over a year now. My setup, with some documentation, is here https://github.com/skx/ms-lite/ https://github.com/skx/ms-lite/ and evolved from a commercial service http://book.mail-scanning.com/ http://book.mail-scanning.com/ I've used Haraka standalone for a couple of custom-jobs, but I've never used it at any significant volume. That said qpsmtpd was a pleasure to use, deploy, and develop against, so I'd expect to have a similar feeling with it.
