As of May 16, 2016 after about 50+ qmail installations I am happy to report that the qmail guide supports TLS on port 587. Many people may not realize this but port 587 is required for most apple devices. This guide fully supports secure POP3 on port 995 (dovecot), Secure SSL on port 465 (qmail) and secure TLS on port 587 (qmail). Once your qmail system is setup you can follow my optimization techniques to help thwart spam from arriving in your user's inbox.
I am planning on adding more spam related services to the qmail guide as a secondary expansion. Think of it as optimizing qmail part 2. This will include guide for razor, pryzor, adding even more rules to spamassassin and a new guide for enabling spamdyke.
Enjoy and as always please consider a donation to keep the site going.

In the Seventeenth episode of Team Cymru's 'The Who and Why Show', we have the fifth in an occasional series designed to directly assist network administrators, looking at various Open Source Tools that can be used to check and secure systems. Today we talk with Justin Mason, the original author of SpamAssassin, a world class anti-SPAM tool that's fundamentally changed the way we deal with the SPAM problem. These short overviews will give you a good grounding in the basics of the tool, the alternatives and also perhaps enlighten long time users to some of the upcoming features for future versions.
The current document on how to create a queuing server was dated so I updated it as of 10/25/2015. The new guide is located at http://freebsdrocks.net/index.php/documents/13-useful-qmail-utilities/140-how-to-create-a-secondary-or-queueing-qmail-server-2
Time for an update to qmail. I have been making some minor changes to the guide. The first mistake I made was changing the skel tarball from maildrop to dovecot. This filtering only works on the webmail level. It does not automatically filter spams. I have changed this back to maildrop so automatic filtering will work
I have been making some changes to the guide in regards to TLS. The stock install of qmail does not support TLS. There have been a few changes to the qmail installation to make qmail work. This is a work in progress. I have TLS working on a few different test vm's and I am tweaking the guide so this will work for everyone.
That's it for now. Let me know if you have any questions.
I have updated the How to add rules to spamassassin as the cfupdates.sh file was full of old and outdated rules. The walkthrough is setup and you can start using it today!
Coming in the future is a walkthrough on how to install FreeBSD on VMWare esxi 6.0.
