Looks good to me. I can't offer any technical advice on the suggest
settings for ReiserFS since I haven't had a chance to play with it yet;
but he seems to know what he is talking about. :-)
I highly recommend against applying the patch he has at the top of the
Qmail Tuning section, though. That is very unethical e-mail practice.
I am not sure about the recommendation to lower the conf-split, since,
again, I am not in any way familiar with ReiserFS's operation. Generally
you want a large split since filesystems perform better with many
directories with a couple of files than a few directories with lots of
files. My advice, test it for yourself; just make sure you are using a
prime number for the split.
I'm not sure on the statement that qmail is unreliable under Linux due to
its assumptiopn that "link is a synchronous operation". I've never read
anything about it. Anyone else?
Like it says, I wouldn't use ReiserSMTP in a production environment.
Lastly, common recommendations: if you are going to be running a big
server, run your queue and Maildirs (run Maildirs, not Mailboxes) on a 15k
RPM SCSI disk with a good controller. Don't be afraid to spend some cash,
here. You will have a lot less headaches if/when one of your customers
decides to start spamming from your server or your own server comes under
siege from UBE.
