I started using qmail to handle email on my own server, and those of my employers, back in 1998. I have been very happy with it, and have yet to find any real cause for complaint. Every time I have found something I needed that it wouldn’t or couldn’t do, I found that either somebody had already written a patch to do what I needed, or I was able to write such a patch myself. If you’re not familiar with it, qmail is a mail transfer agent (MTA), or "mail server software". Unlike other MTAs like sendmail, which encapsulate all of their functions into one massive program, qmail is built as a collection of tiny programs, each of which does its one little piece of the puzzle, and does it well. This makes each individual program much easier to test and debug. The official qmail web page is written and maintained by qmail’s author, Dan Bernstein. Dr. Bernstein has written several other software packages, including daemontools , djbdns , and ucspi-tcp which are all very useful (especially on a machine running qmail.) The un-official qmail.org site is written by other qmail "fans". This is where you will find a large collection of patches, as well as links to other information for people who are running, or thinking about running, qmail. Life with qmail is a document which contains a fairly complete walk-through of installing qmail and configuring it for the first time. I hadn’t seen this until after I had been running qmail for a few years, but the directions here are quite similar to how I have it set up. Very much recommended for people who are trying qmail for the first time and aren’t used to it yet. The big qmail picture is a set of diagrams (in GIF, PS, or PDF format) which show the various programs which make up qmail and how they relate to each other. These images were a major part of my own process of learning about how qmail works- in fact, at one of my former jobs (at an ISP) I printed out all four pages with a 36-inch plotter and hung them on the wall, just to refer to as needed. Back in 2006, I made a few diagrams which are similar to the "qmail big picture", but which include programs outside of qmail that are commonly used with qmail (things like rblsmtpd, simscan, and so forth.) It used to be two separate diagrams, however I have since purchased a new version of OmniGraffle (yes, I pay for my software) and am now able to create multi-page diagrams, and export them as multi-page PDF files. I’ve also expanded the diagram to three pages: Incoming: how mail gets into the queue, whether from a remote client or from a process on the local machine. Outgoing: how mail gets out of the queue, whether it’s going to a local mailbox or to a remote server. Retrieval: how MUAs and most webmail systems access the messages stored in the mailboxes. Note that this diagram is not meant as a deep reference, but as an overview to help you understand how the various programs "fit" with each other.

This page on my regular web site explains how I set up the software. As an example, I have placed the "source code" of this web site under a repository, with a trac interface to look at changes over time. Patches I have moved this section to a page of its own because it was getting to be too long. Scripts I have also moved this section to a page of its own . HOWTO pages I have written a page which explains how to set up an SMTP service . This should be handy if you need multiple servers (i.e. one on port 25 for normal incoming mail, and an SSL-secured on port 465 to allow your users to AUTH and relay mail securely. I’ve also written a page on the options for TLS/SSL and AUTH , and a page on how to use the SMTP AUTH command when testing a server. It also shows how to use openssl to connect to an SMTP server which is using SSL or TLS to secure the connection. I have written a page on getting ClamAV and Qmail-Scanner to work together . I’ve also written one explaining how to upgrade an existing ClamAV install on an RPM-based distro . I have written a page which details how to use my "qfixq" script to repair a damaged queue. This page is listed on the scripts page, but I feel it also deserves a special mention here. I have written a page which talks about how to work with qmail’s log files . It will explain a few different things which can be done with the log files, such as tracing a message as it goes through the server. I have written a page which explains how relaying works under qmail . I tried to explain how the RELAYCLIENT variable and the rcpthosts file affect qmail-send. I have written a page which explains the so-called "silly qmail syndrome" , along with a patch to fix the problem. I have written a page which explains the issues that people seem to run into when they upgrade from qmailrocks 2.2.0 to my current combined patches . I have written a page which explains how to set up what I call a " Mailhub ", which is a machine whose only job is to handle RBL, virus, and spam scanning for mail arriving from the outside world, and forwards all "clean" messages to a dedicated mailbox server. I have written a page which explains how to run vpopmaild under daemontools . vpopmaild is a service included with vpopmail 5.4.15 (and later) which allows clients to perform the same functions as the vpopmail command line programs, without having to SSH into the machine and run the programs directly. It also makes it possible, once I write the code to do it, for qmail-smtpd to validate an AUTH command without having to fork() and exec() another process. The page also includes a quick example of how to test the service once it’s running. I have written a...
