I'm new to the list so feel free to flog me if these questions are
archived somewhere (i haven't been able to turn up anything on a couple
of searches).
1)
I'm running qmail on a debian box; i'm pretty sure it was built from the
qmail-src 1.03-14 debian source package. there has been some debate as
to whether this is normal; i've heard from a couple people that the
qmail-send process is supposed to take up all the avail cpu when nothing
else is using it; is that right? here's a typical output of 'top'... as
you can see the load is a bit high for a machine that's doing nothing
but accept mail for 30-40 people and provide imap / ssl imap service.
the load rarely gets too high, and qmail does seem to allow other procs
to take up some cpu, but generally qmail-send is taking up at least
40-50 percent of the cpu, and the load is often between 1 and 2 even in
the evening when the box is being used for very little.
1:05am up 54 days, 10:06, 1 user, load average: 1.28, 1.32, 1.24
67 processes: 58 sleeping, 4 running, 5 zombie, 0 stopped
CPU states: 33.0% user, 66.9% system, 0.0% nice, 0.0% idle

2)
has anyone had much luck with any type of imapd other than courier for
qmail using Maildir? i was able to get the uw Maildir patches to work,
but it didn't seem to work well with 'dot' subfolders. When creating
folders from netscape the new folders were created in the main home
directory, and '.' subfolders and sub-subfolders didn't show up.
