qmail - HOWTO, suggestions

While I have spent a lot of time managing and tweaking different qmail implementations - the last of which dealing with smtp-auth and tls - I have also found a good number of sites who do a better job at providing some information that I either don't understand too well myself or I haven't had the time to digest. If you are using my site as a guide to installing qmail with imap and virtual domain support, PLEASE take a look at the original sites from which I have based quite a bit of my work:

- Oliver Lehmann's qmail HOWTO - this is the beginning of qmail for me - the genesis of it all, if you will. With Oli's help, I got my first well functioning qmail server going. Of course, you need to be able to read German, but even if you can't, it is likely that you could stumble through his command line examples. Anyone who has used my HOWTO owes Oli a lot of credit.
- Qmail Rocks dot org - this has been my latest weapon of choice as it is obvious that Eric Siegel has done his research in compiling an extensive and powerful qmail installation. His site goes quite a bit beyond what I would have expected and helps do a lot of the work for you.
- Shupp.Org - Bill Shupp is the source of my last modified howto. Unfortunately, this howto no longer works - actually, everything works except the smtp-auth portion. I have spent the past two days trying to figure out why and can't... Alas, this is likely NOT BILL'S FAULT, but something that I am not doing correctly. I am going to add a disclaimer to the top of my recent howto for that reason. Still, Bill has come up with a fantastic patch that worked on one of my machines and is the one having allowed me to do smtp-auth in the first place.
- Dan Bernstein's Page - of course, this list would be without merit if I excluded Dan's site. He is the reason we are even here. I honestly considered changing to Postfix recently because of my problems with smtp auth, but I would have thrown away years of work in understanding how qmail works. Plus, there is one fact that remains - I have NEVER had a qmail installation fail. NEVER. I have also NEVER had a qmail installation get hacked. Never is quite powerful considering I have been using qmail for 4 years on 10 different servers. Some of those servers have been heavily punished by my ineptitude... but qmail has continued to run as advertised. So, while I have my complaints (i.e. the necessity of patches upon patches in order to get certain services to work), I couldn't have done it better and am not about to take the chance that Postfix will set up the need to spend yet another 4 years learning another system.
