I've got no experience with mysql, so I can't help there.

However -- I can offer at least one caveat about qmail on an
OpenBSD.
Note that qmail normally installs in "/var/qmail". Now, all of
/var is mounted "nosuid". Unfortunately, one of the daemons has to be
installed suid, so it will not work there.
On my system, I have added two symlinks in the initial
/var/qmail directory:
================================================== ====================
lrwxr-xr-x 1 root wheel 16 Jun 24 2004 bin@ -> /usr/local/qmail
lrwxr-xr-x 1 root wheel 10 Jun 24 2004 control@ -> /etc/qmail
================================================== ====================
The first is to put the bin directory on a different filesystem, to
allow it to be mounted allowing suid programs Here is the suid program
in question. If you really want to keep almost all of qmail: in /var,
you can do an individual link to that one file someplace safe.
================================================== ====================
-rws--x--x 1 qmailq qmail 14104 Jun 24 2004 qmail-queue*
================================================== ====================
No -- you *don't* want to turn off the "nosuid" mount for /var.
Several security features depend upon it.
The other is to put the configuration files in /etc, along with
all the other standard configuration files.
Note also that "sendmail" runs through a few (security) hoops,
and the best way to set that up is to edit the configuration file that
the "sendmail" redirector uses.
Look into /etc/mailer.conf. Here is my modification to that:
================================================== ====================
# $OpenBSD: mailer.conf,v 1.3 2000/04/06 18:24:19 millert Exp $
#
# Execute the "real" sendmail program, named
/usr/libexec/sendmail/sendmail
#
#sendmail /usr/libexec/sendmail/sendmail
#send-mail /usr/libexec/sendmail/sendmail
#mailq /usr/libexec/sendmail/sendmail
#newaliases /usr/libexec/sendmail/sendmail
#hoststat /usr/libexec/sendmail/sendmail
#purgestat /usr/libexec/sendmail/sendmail
sendmail /var/qmail/bin/sendmail
send-mail /var/qmail/bin/sendmail
mailq /usr/libexec/sendmail/mailq
================================================== ====================
This is needed because sendmail is called from many other
programs to inject mail into the net, and you want all of them to get
the qmail substitute for sendmail.
>I have a startup script in place which is listed in my qmail thread (link
>above) - but I'm having trouble with it.
I've done what you are not supposed to, and modified /etc/rc.
Just after the part which starts spamd (which I don't use), I
have the following:
================================================== ====================
# Start qmail instead of sendmail -- DoN.
if [ "X${qmail_flags}" != X"NO" -a -f /etc/mailer.conf ]; then
echo -n ' qmail'; ( csh -cf '/var/qmail/rc &' )
fi
================================================== ====================
And in /etc/rc.conf, I have:
================================================== ====================
# For normal use: "-L sm-mta -bd -q30m", and note there is a cron job
#sendmail_flags="-L sm-mta -C/etc/mail/localhost.cf -bd -q30m"
spamd_flags=NO # for normal use: "" and see spamd-setup(8)
#
# Run qmail instead of sendmail
#
qmail_flags="YES"
================================================== ====================
I put this here, instead of in /etc/rc.local, because it was
truly replacing something normally started from /etc/rc,
I hope that this helps.
I can't look at your website to see what your progress was,
since I've got a gigantic download going (Solaris-10, FWIW) in my
browser. Hmm ... maybe one of the OpenBSD systems can visit it.
Yep -- but I don't see much specific to your qmail question.
Separating them into two threads might help more.

That, I will have to leave to others.
I hope that my qmail info is some help.
Good Luck,
DoN.
